Abstract :
This paper introduces interleaved zero current transition (ZCT) converters where two sets of switches are operating out of phase and share the load power equally. Turn-on transitions at zero current and a significant reduction of the losses associated with diode reverse recovery are accomplished through addition of two small inductors. The paper describes a 30 kW (300 V, 100 A) interleaved ZCT buck converter operating at 32 kHz switching frequency. Losses and efficiency of the experimental prototype compare favorably against the standard hard-switched buck converter, and against previously proposed ZCT approaches.
