This paper presents a novel simplied PWM technique to drive switched capacitor type multi-level inverter fed from isolated type DC-DC converter for distributed generation. Distributed generation (DG) is renowned power generation at point of utility with no environmental aects and reduces transmission line losses. Photo-voltaic system is considered as renewable energy source for DG and the low voltage from PV system is boosted to required voltage using an isolated type single-input multi-output (SIMO) DC-DC converter. DC output from isolated SIMO DC-DC converter is fed to switched capacitor type multi-level inverter (SC-MLI) to feed the AC load. Isolated SIMO DC-DC converter apart from boosting the DG output voltage, also eliminates the problem of voltage unbalancing in SC-MLI topology. Closed loop operation of SIMO DC-DC converter employs only single PI controller instead of three controllers was presented in this paper. Modes of operation of SC-MLI and Novel PWM switching pattern was explained. Simulation of proposed system was developed using MATLAB/SIMULINK software. The prototype was developed for the proposed system and hardware results are also shown.

Solar energy hasbecomepopular nowadays and desire for clean energy. Since the solar radiation on no occasion remains constant,it keeps on insecure throughout the day. The need of the hour is to distribute a constant voltage to the grid irrespective of the deviation in temperatures and solar insolation. The inverter is designed from a boost converter along with a line frequency. The voltage from the boost converter is fedto the grid through inverter. In this proposed method high efficiency can be achievedby using only one switch functioning at high frequency at a time. The converter uses IGBT and ultra-fast reverse recovery diode. The simulation and experiment results are verified using MATLAB/Simulink software.

Modeling and Simulation of Wind Energy Conversion System Interconnected with ...idescitation
The global electrical energy consumption is steadily rising and consequently there
is a demand to increase the power generation capacity. A significant percentage of the
required capacity increase can be based on renewable energy sources.The integration of
Distributed Generations into grid has a great importance in improving system reliability.
The power generation with renewable energy sources is essential in now-a-days to control
the atmospheric pollution and global warming. To get fast tracking for maximum power, it
is preferable to use incremental conductance method. MPPT control for variable speed
wind turbine is driven by Induction Generator. The wind turbine generator is operated
such that the rotor speed varies according to wind speed to adjust the duty cycle of power
inverter and maximizes wind energy conversion system efficiency. The system includes the
wind turbine, induction generator, three phase rectifier, DC link voltage controller, three
phase inverter. In this paper, modeling and simulation of wind energy conversion system
(WECS) with incremental conductance maximum power point tracking (MPPT) is
presented. This WECS is connected to electric utility to measure the performance. In this
paper, the objective such as optimal location and sizing of DG units are studied to check the
system performance in reducing the power losses, increase in voltage profile and reliability.
For analyzing the performance of WECS, a case study is carried out on IEEE 15 bus radial
distribution system. The case studies shows that there is gradual improvement in voltage
profile, reduction in power losses and variation in reliability indices and results were
simulated in the MATLAB/SIMULINK. The results shown in this paper can contribute well
to electrical utilities with radial distribution systems.

The transmission usage cost allocation is one of the major issues experienced by the Electric Supply Industries. In this paper, authors have considered Line Outage Distribution Factor (LODF) for allocating the transmission usage cost allocation under contingency condition. Authors have modified the distribution factor for maximum flow and propose a novel Maximum Line Outage Distribution Factor (MLODF) which depends upon the redistribution of the generation in the line flow considering N-1 security constraints. Similarly, for transmission loss cost allocation under contingency condition Maximum Line Outage Loss Distribution Factor (MLOLDF) is developed. Full recovery policy of transmission cost allocation is considered. The reliability and accuracy of the proposed method is tested on the sample 6 bus system.
Implementation of Cascaded H-bridge MULTI-LEVEL INVERTEREditor IJMTER
The classical two level inverter produce output with levels either Vdc or -Vdc. The output
voltage waveform of ideal inverter should be sinusoidal but the waveform of conventional inverters
is non-sinusoidal and contains certain harmonics. Large capacitor is normally connected across the
DC voltage source and such a capacitor is costly and demands space. In order to overcome these
drawbacks Multi level inverters are introduced. The great advantage of this kind of inverter is the
minimum harmonic distortion obtained. Power electronics is the applications of power
semiconductor devices for the control and conversion of electric power such that these devices
operate as switches. An inverter is an electrical device that converts DC voltage to AC voltage; the
resulting AC can be at any required frequency. Multi-level inverters are nothing but the modification
of basic bridge inverters [1]. The multilevel inverter collectively converts the several levels of dc
voltage to a desired ac voltage. The unique structure of multilevel inverters allows them to reach
nearer to sinusoidal i.e., with low harmonics. In this project the work is done on five & nine level
multilevel inverter but the multilevel can be done up to any level and how many levels we increase
that much precise sinusoidal supply we can get i.e., we can reduce that many harmonics from the
supply. Simulation work is done using the MATLAB software
Impact of Distributed Generation on Energy LossNadineCroes
The aim is to give more insight into the effect of distributed power generation on energy loss. In most cases these distributed generators (DGs) are based on renewable energy such as solar panels and wind turbines, but there are also new technologies to increase efficiency such as the micro combined heat and power systems. Distributed generation can increase efficiency in the grid by reducing the distance between generators and consumers of electricity. The objective is to find an optimal mix of distributed generators (DGs) in a district so that energy loss is minimized and overload is avoided. The effect of using future electronic devices, such as electric vehicles, is also studied. To find an optimal mix of DGs a mixed integer quadratic programming model is defined and a case study is presented. The results indicate that the optimal solutions give substantial reductions in loss without overloading the system.
Simulation of MPPT Algorithm Based Hybrid Wind-Solar-Fuel Cell Energy SystemIJMER
This paper presents a new system configuration of the front-end rectifier stage for a hybrid
wind/photovoltaic energy system. This configuration allows the two sources to supply the load
separately or simultaneously depending on the availability of the energy sources. The inherent nature of
this Cuk-SEPIC fused converter, additional input filters are not necessary to filter out high frequency
harmonics. Harmonic content is detrimental for the generator lifespan, heating issues, and efficiency.
The fused multiinput rectifier stage also allows Maximum Power Point Tracking (MPPT) to be used to
extract maximum power from the wind and sun when it is available. An adaptive MPPT algorithm will
be used for the wind system and a standard perturb and observe method will be used for the PV system.
Operational analysis of the proposed system will be discussed in this paper. Simulation results are given
to highlight the merits of the proposed circuit.

Analysis of CMOS Comparator in 90nm Technology with Different Power Reduction...IJECEIAES
To reduce power consumption of regenerative comparator three different techniques are incorporated in this work. These techniques provide a way to achieve low power consumption through their mechanism that alters the operation of the circuit. These techniques are pseudo NMOS, CVSL (cascode voltage switch logic)/DCVS (differential cascode voltage switch) & power gating. Initially regenerative comparator is simulated at 90 nm CMOS technology with 0.7 V supply voltage. Results shows total power consumption of 15.02 µW with considerably large leakage current of 52.03 nA. Further, with pseudo NMOS technique total power consumption increases to 126.53 µW while CVSL shows total power consumption of 18.94 µW with leakage current of 1270.13 nA. More then 90% reduction is attained in total power consumption and leakage current by employing the power gating technique. Moreover, the variations in the power consumption with temperature is also recorded for all three reported techniques where power gating again show optimum variations with least power consumption. Four more conventional comparator circuits are also simulated in 90nm CMOS technology for comparison. Comparison shows better results for regenerative comparator with power gating technique. Simulations are executed by employing SPICE based on 90 nm CMOS technology.
A New Family of Step-up Hybrid Switched- Capacitor Integrated Multilevel Inve...Asoka Technologies
In the low voltage based renewable systems like PV and Fuel cell applications, the step-up of the output voltage to drive the loads is essential. For this, the integration of switched-capacitor (SC) units with the dc-ac converters will have the potential advantages like improved efficiency, optimal switching devices, small size of passive elements (L and C) as compared with traditional two-stage conversion system (dc/dc converter and dc/ac converter). This paper focuses on a new family of step-up multilevel inverter topologies with switched capacitor integration with dual input voltage sources. With the flexibility of 2 dc sources and switching capacitor circuits, four different topologies have been suggested in this paper with features of high voltage gain, reduced component count, reduced voltage stress and self-voltage balancing of the capacitor while achieving a higher number of levels. A detailed analysis of proposed multilevel inverters has been analyzed with the symmetrical and asymmetrical mode of operations and the associated gain, the number of levels, and other performance indices are presented. An in-depth study of all the topologies has been accomplished in this paper with several comparative studies in terms of components count, voltage gain and cost. The effectiveness and practicability of the suggested topology with 13 level output voltage has been explained by the experimental results obtained from a scale down prototype.

Anintegration and operation of a three-phase inverter with twobuck/boost maximum power point trackers
(MPPTs) for dc-distribution applications. In a dc-distribution system, a three phase inverter isrequired to control
the power flow between dc busand three phase ac grid, and to regulate the dc bus to a certainrange of voltages.
A droop regulation mechanism according to the inverter inductor current levels to reduce capacitor size, balance
power flow, and accommodate load variation is proposed. Since thephotovoltaic (PV) array voltage can vary
from 0 to 5000 V, especially with thin-film PV panels, the MPPT topology is formed with buck and boost
converters to operate at the dc-bus voltage around 4000 V, reducing the voltage stress of its followed inverter.
Additionally, the controller can online check the input configuration of the two MPPTs, equally distribute the
PV-array output current to the two MPPTs in parallel operation, and switch control laws to smooth out mode
transition. A comparison between the conventional boost MPPT and the proposed buck/boost MPPT integrated
with a PV inverter is also presented. Asingle-phase bidirectional inverter with two buck/boost maximum power

New ac dc power factor correction architecture suitable for high frequency op...Asoka Technologies
This paper presents a novel ac-dc power factor correction (PFC) power conversion architecture for single-phase grid interface. The proposed architecture has significant advantages for achieving high efficiency, good power factor, and converter miniaturization, especially in low-to-medium power applications. The architecture enables twice-line-frequency energy to be buffered at high voltage with a large voltage swing, enabling reduction in the energy buffer capacitor size, and elimination of electrolytic capacitors. While this architecture can be beneficial with a variety of converter topologies, it is especially suited for system miniaturization by enabling designs that operate at high frequency (HF, 3 – 30 MHz). Moreover, we introduce circuit implementations that provide efficient operation in this range. The proposed approach is demonstrated for an LED driver converter operating at a (variable) HF switching frequency (3 – 10 MHz) from 120Vac, and supplying a 35Vdc output at up to 30W. The prototype converter achieves high efficiency (92 %) and power factor (0.89), and maintains good performance over a wide load range. Owing to architecture and HF operation, the prototype achieves a high ‘box’ power density of 50W/ in3 (‘displacement’ power density of 130W/ in3), with miniaturized inductors, ceramic energy buffer capacitors, and a small-volume EMI filter.
Novel High Performance Stand Alone Solar PV System with High Gain, High Effic...Asoka Technologies
This paper proposes a novel 3- stand-alone solar PV system configuration that uses high gain, high efficiency (96%) dc-dc converters both in the forward power stage as well as the bidirectional battery interface. The high voltage gain converters enable the use of low voltage PV and battery sources. This results in minimization of partial shading and parasitic capacitance effects on the PV source. Series connection of a large number of battery modules is obviated, preventing the overcharging and deep discharging issues that reduce the battery life. Also, the proposed configuration facilitates "required power tracking (RPT)" of the PV source as per the load requirements eliminating the use of expensive and 'difficult to manage' dump loads. High performance inverter operation is achieved through abc to dq reference frame transformation, which helps in generating precise information about the load's active power component for RPT, regulation of ac output voltage and minimization of control complexity. Inverter output voltage is regulated by controlling the modulation index of sinusoidal pulse width modulation, resulting in a stable and reliable system operation. The active power demand is controlled by regulating the dc link voltage. All the analytical, simulation and experimental results of this work are presented.
This article proposes a topology for single-phase two stage grid connected solar photovoltaic (PV) inverter for residential applications. Our proposed grid-connected power converter consists of a switch mode DC-DC boost converter and a H-bridge inverter. The switching strategy of proposed inverter consists with a combination of sinusoidal pulse width modulation (SPWM) and square wave along with grid synchronization condition. The performance of the proposed inverter is simulated under grid-connected scenario via PSIM. Furthermore, the intelligent PV module system is implemented using a simple maximum power point tracking (MPPT) method utilizing power balance is also employed in order to increase the systems efficiency.
Development of wind and solar based ac microgrid with power quality improveme...Asoka Technologies
This work proposes a microgrid (μ-grid) integrating wind and solar photovoltaic (PV) resources, along with the battery energy storage (BES) to the three phase grid feeding the nonlinear load. The μ-grid disconcerted by probabilistic nonlinear time dependent parameters and their effects are compensated by cohesive controllers used for utility grid side voltage source converter (GVSC) and machine side VSC (MVSC). The switching controls and the reconfigurability of the μ-grid are addressed on imperative aspects of improving power quality (PQ), power reliability, nonlinear load compensation and economic utilization of resources. The nonlinear load compensation and PQ enhancement are achieved by executing modified version of the adaptive filtering technique including “momentum” based least mean square (MLMS) control technique, utilized for providing the switching control signals to the GVSC. It utilizes two preceding gradient weights for obtaining updated weight thereby improving the convergence rate and overcoming the limitation of conventional control of the same family. The MVSC acquires its switching signals from conventional vector control scheme and the encoderless estimation of speed and rotor position of the synchronous generator (SG) driven by wind turbine through back electromotive force control technique. The external environmental disturbances are overcome by utilizing perturb and observe (P&O) maximum power point (MPP) for wind optimal power extraction and adaptive P&O with variable perturbation step size for solar MPP estimation. Test results are obtained from the laboratory prototype under steady state and dynamic conditions including altering wind speed, intermittent solar insolation and variable load conditions. The PQ issues are addressed and investigated successfully.
An integrated boost resonant converter for photovoltaic applicationsAsoka Technologies
Effective photovoltaic power conditioning requires efficient power conversion and accurate maximum power point tracking to counteract the effects of panel mismatch, shading, and general variance in power output during a daily cycle. In this paper, the authors propose an integrated boost resonant converter with low component count, galvanic isolation, simple control, as well as
high efficiency across a wide input and load range. Provided is a discussion of the converter synthesis, key operational features, converter design procedure, and loss analysis, as well as experimental verification by way of a 250-W prototype with a California Energy Commission efficiency of 96.8%.
