Abstract :
This paper presents an improved magnetic snubber circuit for the diode reverse recovery in DC-to-DC power converters. The proposed circuit reduces effectively the core loss of the magnetic snubber. In addition, this circuit improves the control characteristics of the zero-voltage-switching converter using saturable inductors controlled by PFM. The operation of this circuit is described by use of equivalent circuits and verified by experiments
