Abstract

This paper presents a new zero-voltage transition (ZVT), high frequency transformer isolated, fixed frequency dc-to-dc bridge converter topology with pulse width modulation (PWM). This converter is based on a PWM scheme suitable for single-stage operation of ac-to-dc converter. The auxiliary circuit of this topology is placed out of the main power path and, therefore, has small power rating. This converter is suitable for high power applications. Operating modes of this converter are identified and analyzed. Based on these analyses design example of a 50 kHz, 1 kW dc-to-dc converter is presented. Results obtained from PSPICE simulation are presented to verify the advantages claimed for this converter.
