Analysis and Implementation of Pulse-Width Modulated DC-DC Converter for Electric Vehicles with Improved Efficiency
This paper presents new gating techniques to improve the efficiency of zero-voltage zero-current switching (ZVZCS) full-bridge DC-DC converter for battery charging in electric vehicles. The converter is assisted by a passive auxiliary circuit to extend the zero voltage switching range. The uncontrol...
