Abstract :
Earlier references have described a new soft switched ZVS/ZCS (zero voltage switching, zero current switching) converter for IGBTs that allows operation above 20 kHz. Although frequencies above 20 kHz are now possible for IGBT converters, the optimum frequency for minimum volume may be below 20 kHz because of heat sink requirements. A comparative study considers the reactive component versus heat sink volume tradeoff for two 6 kW converters, one using ZVS/ZCS and the other using a more conventional circuit with hard switching.<>
