A Zero Voltage Switched PWM Isolated Boost Converter with Voltage Mode Control
A new boost dc-dc pulse width modulated (PWM) converter is proposed. The converter operates with zero voltage switching (ZVS), fixed frequency and continuous input current. The converter topology core has zero turn-on loss even when used with hard switching. An auxiliary switch clamps the voltage across the full bridge to zero prior to the switching off the bridge switches. The auxiliary switch operates for a small fraction of the period and turns on with zero current switching (ZCS) and turns off with ZVS. Direct duty cycle voltage mode control technique is implemented. The experimental results on the lab prototype verify the performance of converter and effectiveness of ZVS and voltage mode control techniques. In this paper the operation of the converter is explained and experimental results on a lab prototype are presented.
