The characteristics and limitations of the half-bridge zero-voltage-switched (ZVS) quasi-resonant converters (QRCs) are described. A novel multiresonant concept is proposed for the half-bridge topology to improve the ZVS QRC's load range. Experimental results for 300 V. 75 W zero-voltage-switched quasi-resonant and multiresonant converters operating in the frequency range from 2 MHz to 8 MHz are presented
