A novel ZVS multi-resonant converter with rectifiers' deadtime control operated in 20 MHz range

Abstract

A novel zero-voltage-switched multi-resonant power converter is presented. The rectifier deadtime control proposed in this paper enables this power converter to achieve zero-voltage-switching in any load range and to operate from full load to no load within a high and narrow frequency range. Experimental results of two power converters designed for 2 MHz and 20 MHz operation and analysis are presented.<>
