Abstract :
This paper presents a new zero-voltage switching (ZVS) semi-bridgeless ac-dc boost converter targeted for application in plug-in hybrid electric vehicle battery chargers. Switching losses are nearly eliminated due to a novel and simple auxiliary circuit that enables ZVS for the converter powertrain and auxiliary switches. The detailed operation of the proposed converter, a stress analysis of the auxiliary circuit components, and a detailed control strategy are presented. The feasibility of the converter is confirmed by an experimental prototype operating at 70 kHz switching frequency, 240 V input, and 400 V/3.4 kW output.
