A novel zero‐voltage‐switching current resonant converter is presented. The rectifier deadtime technique proposed in this paper enables this converter to achieve zero‐voltage switching on all semiconductor devices, including rectifier diodes, in any load range, and to operate form full load to no load within a high and narrow frequency range. The circuit operation is analyzed and is verified experimentally by two converters designed for 1 MHz and 10‐MHz switching frequency operation. In the experiments, zero‐voltage switching is achieved even at light load or no load, and a maximum efficiency of 93.5% in the 1‐MHz‐class converter and of 85.2% in the 10‐MHz‐class converter is realized. © 1998 Scripta Technica.
