A New Mode Changable Asymmetric Full Bridge DC/DC Converter having 0 ~ 100 % Duty Ratio

A New ZVS-PWM Full-Bridge Converter

A full-bridge converter which employs a coupled inductor to achieve zero-voltage switching of the primary switches in the entire line and load range is described. Because the coupled inductor does not appear as a series inductance in the load current path, it does not cause a loss of duty cycle or severe voltage ringing across the output rectifier. The operation and performance of the proposed ...

Development of Average Model for Control of a Full Bridge PWM DC-DC Converter

This paper presents a detailed small-signal and transient analysis of a full bridge PWM DC-DC converter designed for high voltage, high power applications using an average model. The derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. Results obtained in the analysis of the high voltage and high power design examp...

Reduction of Voltage Stress in the Full Bridge BIBRED by Duty Ratio and Phase Shift Control

A new control scheme is presented which provides simultaneous control of the output voltage and the energy storage capacitor voltage in the full-bridge Boost Integrated with Buck RectifiedEnergy storage/Dc-dc converter (full-bridge BIBRED). The new control scheme solves the problem of wide voltage excursions for the energy storage capacitor voltage under variable load conditions. A low frequenc...

Comparison of Full Bridge and Two Inductor Boost Converter Systems

The DC-DC converter topologies have received increasing attention in recent years for high power and high performance applications. The advantages of DC-DC boost converters include increased efficiency, reduced size, reduced electromagnetic emission, faster transient response, and improved reliability. The front end inductors in a boost converter are magnetically coupled to improve electrical p...
