Abstract :
The proposed converter is a hybrid converter consisting of a pulsewidth modulation (PWM) DC-DC power converter and a set of current mode resonant circuits including a control switch. The power conversion is achieved by a PWM control scheme, and zero current switching is realized by the assistance of a current mode resonant technique. This converter has the easy control characteristics of PWM and the low switching loss of resonant-type converters. The experimental results of a prototype converter with 200 V, 5 kW output show benefits such as a high efficiency of 95%, stable operation, and low noise characteristics
