This thesis proposes, analyzes and verifies a control scheme to regulate the output voltage of the boost inverter. The proposed control scheme maintains sinusoidal output voltage for variable frequency and constant ...

Base transit time of an HBT is more than 70% of its total transit time. Therefore it plays a very crucial role in determining the transistor’s high frequency performance. In the present work, base transit time of a Gaussian ...

A scheme for improving the input current wave shape of three phase bridge rectifier is proposed and analyzed in this thesis. Generally, to convert line frequency from ac to dc, a diode bridge rectifier is used. To reduce ...

Different models of nano-electronic quantum device Single Electron Transistor (SET) are studied in this work, a modified macro model is proposed and at the end its application in a communication circuit is presented. In ...

As the device feature size enters into the nanoscale, the modeling and simulation of carrier transport in FinFETs devices becomes challenging. FinFETs technologies under development have channel lengths well below 100 nm ...

A theoretical analysis is presented to find the impact of crosstalk due to optical cross-connects (aXCs) in a WDM network. An N x N AWG based axc is first considered with one wavelength per channeL Thereafter, a mux/demux ...

High frequency switching power supplies have become part of electronic equipments to provide regulated DC of desired voltages at a lost cost and high efficiency. These power supplies have several advantages over their ...

In this thesis, two separate switch mode converters with voltage lift circuits with two sources and complex gate pulse control has been investigated. To reduce the number of supplies to one and ease the control signals, ...

Two dimensional Poisson-Schrödinger equation is solved numerically in depletion all around (DAA) operation of n-channel four gate transistor (G4-FET) by finite element method. Potential distribution is obtained by solving ...

Detection of minor faults in power transformer active part is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. Sweep Frequency Response Analysis (SFRA) is an ...
