An AC-DC Interleaved ZCS-PWM Boost Converter With Reduced Auxiliary Switch RMS Current Stress

The paper proposes a novel interleaved AC-DC ZCS-PWM boost converter that requires the use of just single active auxiliary switch to assist in turning off main power circuit switches with ZCS. can be turned on and ZCS its allows operate without an increase peak current or voltage stress. is for much shorter time than most other converter, which at higher levels previously proposed switch. converter's operation explained key features design considerations are discussed. Experimental results confirm presented as well.
