Digital Simulation and implementation of a Power Factor Correction (PFC) half bridge converter based adjustable speed voltage controlled VSI fed PMBLDC motor is presented in this paper. A single-phase AC-DC converter topology based on the half bridge converter is employed for PFC which ensures near unity power factor over wide speed range. The proposed speed control scheme has the concept of DC...

This paper describes an investigation into the development of a new generation of threephase rectifier, used to power telecommunications equipment. Traditionally, the topology used is a single-phase two-stage design, with a boost converter at the input to the first stage and an isolated dcdc converter making up the second stage. The boost converter provides power factor correction which is nece...

This paper proposes simulation and comparison of BTB (back-to-back) system combining bidirectional isolated dc/dc converters and modular multilevel cascade PWM converters [1]. The system consists of multiple converter cells connected in cascade per phase at both front ends. Each converter cell consists of a bidirectional isolated medium-frequency dc/dc converter and two voltagesource H-bridge (...

In this thesis a predefined design parameters are used to present theoretical guidelines for design of low voltage, and low power DC-DC converter with high power efficiency and low levels of EMI (Electro-Magnetic Interference). This converter is used to alter the DC voltage supplied by the power source. Several DC-DC converters of different types and topologies are described and analyzed. Switc...

─ This paper presents a voltage doubler in to a half bridge converter is derived for electric vehicle battery chargers. The proposed converter provides wide ZVS range, reduced circulating current and also voltage stress. Circulating current during the freewheeling phases of phase shift full bridge circuit are reset by the sum of LLC circuit output voltage and resonant capacitor voltage by achie...

The central part of an energy storage system is the DC-DC converter which connects the ultracapacitor pack or the battery pack and a DC bus of an energy system. In this paper the bi-directional converter which operates in discontinuous conduction mode is designed in order to reduce the costs and remove the current control loop in each phase. High current ripples associated with this mode operat...
