Abstract :
Use of appropriate snubber circuit and paralleling of power switches are very important issues for high power boost power convertor-based power factor correctors. This paper shows that practical approach to the snubbing problem is a simple turn-on snubber with di/dt control of the diode reverse-recovery transition. Implementation of such a snubber in boost power converters with paralleled MOSFET switches is then discussed
