REDUCTION OF REVERSE RECOVERY LOSSES IN SOFT SWITCHED PWM CONVERTERS BY SATURABLE REACTORS

The objective of this study was to investigate the effect of the saturable reactor on the reverse recovery process of diode. This was done by PSPICE (MicroSim Inc.) simulation of an equivalent circuit that represents the problem on hand including a qualitative account of all major losses. The simulation that was verified by experimental results, point out to the merit of connecting a bypass resistor in parallel with the saturable reactor. The simulation methodology developed in the paper could be helpful in studying other reverse recovery problems.
