Abstract

This paper presents a new soft-switched ZVT DC-DC boost converter with auxiliary transistor and optimized gate drive circuit. This type of converter suits very well applications like automated battery chargers or PFC-Power Factor Correction converters. A conventional PWM controller is used for the ZVS boost converter control. Because the power semiconductor devices voltage and current stresses are similar to that of the regular hard commutated boost converters, the application range is very large.
