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, ...

This thesis investigates the starting performance of inverter fed induction motors. Smooth starting with good control is an important requirement for an induction motor. The major requirement of industries are soft start ...

This thesis proposes a two-stage high-power factor and low THD electronics ballast for a 40W commercial fluorescent tube lamp. The proposed ballast uses a Ĉuk Buck-Boost ac-dc converter in continuous conduction mode (CCM) ...

Most regulators are designed to meet the requirements that the output voltage must be held constant within a specified tolerance for changes within a specified range in the input voltage and the output loading, the output ...

Harmonic pollution has become a serious problem in power systems due to non linear loads connected to the utility line. The injected harmonics can result in a low power factor and various other problems such as: ...

AC voltage controllers regulate ac power to load. Usually they are phase controlled single phase and three phase type. Phase controlled AC- AC voltage controllers are subclass of matrix converters which converts voltage ...

In this thesis, a new topology of four quadrant DC-DC sepic converter has been developed to provide four quadrant operation of a high frequency dc-dc converter having one supply source and proper control of the converter. The ...

The aim of this thesis is to develop a single phase multilevel voltage source inverter fed by multiple capacitive isolated DC source. The multiple sources have been generated from a single DC source using capacitor isolated ...

The Buck-Boost dc-dc converter has a series switch with the source and a series diode with the load. The series switch makes the input current discontinuous. Filtering out the high frequency switching component from the ...

AC voltage controllers regulate ac power to load. Conventionally they are phase controlled single phase and three phase types. Phase control ac- ac voltage controllers are subclass of matrix converters which converts ...
