Popis: | A DC-DC converter topology is presented combining the soft switching effects of the Snubber Assisted Zero Voltage and Zero Current Transition (SAZZ) topology and the increased inductor frequency of the dual interleaved boost converter with interphase transformer. The snubber capacitors and output capacitances of the main devices are discharged prior to turn on using a single auxiliary inductor, eliminating turn on losses. Furthermore, the turn off losses are significantly reduced since the energy stored in the device output capacitance at turn off is recovered at turn on. The effectiveness of the topology is demonstrated on a SiC prototype operating at 12.5 kW, 112 kHz, reducing the switching losses by 50%. |
