Reverse characteristics of a snappy recovery diode with the current snubber in comparison with a soft recovery diode and SiC Schottky type diode

摘要

A new low-cost snubber circuit for diode recovery in hard switching converters is proposed. A diode with snappy recovery behaviour in coupling with the proposed current snubber has close to ideal recovery process, so such a diode seems to be more promising than a soft recovery diode for high-voltage high-power applications to which efficiency and reliability are the main care.
