Abstract

The use of the polarised R-C-D turn-off snubber configuration across switching devices is popular because of its simplicity and use of only passive components. This configuration is limited by the fact that all capacitor stored energy is dissipated in the discharge resistor. In this paper it is shown that with the addition of a ferrite transformer to the standard R-C-D arrangement, in excess of 70% of the energy stored on the snubber capacitor may be passively recovered into the dc supply. Performance of this passive recovery snubber is supported by theoretical, simulated and practical results.
