The wi-fi energy transfer (WPT) is an emerging era with increasingly more ability packages to transfer energy from a transmitter to a cellular receiver over a noticeably huge air gap. but, its extensive utility is hampered due to the relatively low performance of modern wireless power switch (WPT) structures. This study gives an idea to maximize the performance in addition to to increase the quantity of extractable electricity of a WPT system operating in resonant operation. The proposed method is primarily based on actively modifying the equal secondary-side load impedance by controlling the section-shift of the active rectifier and its output voltage degree. The offered hardware prototype represents an entire wireless charging machine, consisting of a dc–dc converter that is used to price a battery at the output of the system. Experimental results are shown for the proposed concept in comparison to a traditional synchronous rectification approach. The supplied optimization technique sincerely outperforms trendy solutions in phrases of efficiency and extractable power.

A bidirectional single-stage three-phase Rectifier with high-frequency Isolation and power factor Correction
This paper proposes a single-stage three-phase rectifier with high-frequency isolation, power factor correction, and bidirectional power flow. The presented topology is adequate for dc grids (or smart-grids), telecommunications (telecom) power supplies, and more recent applications such as electric vehicles. The converter is based on the three-phase version of the dual active bridge (DAB) associated with the three-state-switching cell (3SSC), whose power flow between the primary and secondary sides is controlled by the phase-shift angle. A theoretical analysis is presented and validated through simulation and experimental.

Distributed energy resources (DER) based micro grid and Nano-grid framework is most technically viable bottom-top approach to sustainably meet ever-increasing demand of rural and urban communities. Recently the growth of DC operative home appliances like mobile and lap top chargers, ovens and hair dryer’s etc. are increasing and therefore a DC/DC converter is an efficient way to meet the electricity need from the local DER and helps in improving the system efficiency. This paper presents simulation results of a buck boost converter, MPPT algorithm (P & O method) for solar PV module and closed loop PI control system for obtaining constant 12 V and 24 V DC output voltage at DC bus. The proposed methodology is to extract maximum DC power from solar PV system and it is directly fed to DC load or DC Nano grid.

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%.
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.

MSc Thesis –
A NOVEL SINGLE STAGE INVERTER TOPOLOGY
A single stage single phase inverter configuration is proposed, which employs five semiconductor switches, in
which one operates at high frequency and the rests operate at the fundamental frequency of the output
The inverter is capable of both stepping up and stepping down the voltage and designed such a way that the
required link capacitance is very low
Because of low capacitance instead of using a electrolytic capacitor, a film capacitor is used
In the proposed inverter a high frequency transformer (HFT) can be used for providing galvanic isolation
The proposed inverter is modified slightly to offer soft-switching benefits, which significantly increases the
efficiency
