This document describes a study on a modified cascaded H-bridge multilevel inverter for household appliances. The researchers developed a 9-level single phase inverter using 4 H-bridge cells. They used sinusoidal pulse width modulation to generate switching signals and reduce harmonic distortion. Simulations in MATLAB/Simulink showed the output voltage waveform and total harmonic distortion of 9.12%. A hardware prototype was built and tested to verify the design, demonstrating a 53.9V output voltage with 8.22% total harmonic distortion. The modified topology reduces switching losses and improves output capability compared to other multilevel inverter configurations.
Sigma-Delta Analog-to-Digital converter (ADC), is widely used in portable electronic products. An operational
transconductance amplifier (OTA) is one of the most important components of ADC. This paper presents a
new design of two stages OTA. The design incorporates Sleep insertion technique and leakage feedback current
approach for improving design parameters such as gain, and power as compared to earlier work. The design is
simulated in 0.18µm CMOS technology with supply voltage 1.8V.
These slides present about islanding detection techniques in microgrid systems. Later on the classes other aspects of microgrid protection will be discussed in more detail
Abstract:
This paper reports on the design of an ultra wideband power amplifier using 0.25um GaN- HEMT Technology device obtained from the Triquint Semiconductor. There is huge interest in transistors based on Gallium Nitride in recent years due to its high breakdown voltage and its capability to operate in High frequency applications. The load pull analysis is carried out to obtain both the required source and load impedances. The
power amplifier with over 10W output power and 42% power added efficiency in the frequency range of 3-5GHz is presented in this paper. The PA is designed using a computer aided design tool called Advanced System Design (ADS).ADS provide two different simulation opportunities. These are referred as schematic simulation and
electromagnetic simulation called Momentum. Schematic Simulations are performed on the proposed PA in this paper.

Development and implementation of two-stage boost converter for single-phase ...IJECEIAES
This paper offers a two-stage boost converter for a single-phase inverter without transformer for PV systems. Each stage of the converter is separately controlled by a pulse width modulated signal. A Simulink model of the converter using efficient voltage control topology is developed. The proposed circuit performance characteristics are explained and the obtained simulation results are confirmed through the applied experiments. Moreover, this paper has examined the control circuit of a single-phase inverter that delivers a pure sine wave with an output voltage that has the identical value and frequency as a grid voltage. A microcontroller supported an innovative technology is utilized to come up with a sine wave with fewer harmonics, much less price and an easier outline. A sinusoidal pulse width modulation (SPWM) technique is used by a microcontroller. The developed inverter integrated with the twostage boost converter has improved the output waveform quality and controlled the dead time as it decreased to 63 µs compared to 180 µs in conventional methods. The system design is reproduced in Proteus and PSIM Software to analyze its operation principle that is confirmed practically.

Cascaded h bridge multilevel inverter in a three phase eleven leveleSAT Journals
Abstract
This paper essentially concentrates on the design and implementation of a unique topology for a three phase eleven level
cascaded H-bridge multilevel cluverter by employing different kinds of switching schemes. The basic purpose of this paper is to
enhance the number of voltage level at the output without addition of any complexity to power circuit.
The main advantages of this proposed topology is to scale down the THD and reducing electromagnetic interface EMI generation
and high voltage with very close to sine waveform. In this paper, severel kinds of carrier pulse width modulation techniques are
proposed as which scale down the total harmonic distortion and improve the out voltage from the proposed topology and POD
modulation techniques reduce the THD. A number of H-bridge arranged in cascaded to increase the voltage level with the
different switching schemes analyzed in this paper. It is observed that this new topology can be recommended to three phase
eleven level cascaded H-bridge inverter for the best and optimum performance over the conventional methods. This performance
in optimized in the eleven level of inverter.
Improving the fundamental waveforms and reducing the total harmonic distortion by using 60 IGBTs and switching is arranged
by a topology in cascaded manners.
The simulation model is produced by MATLAB2009 software version.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
