A novel soft-switching buck boost converter using a pulse current regenerative snubber is presented. The proposed soft-switching circuit consists of passive components that configure snubber and regenerative resonant circuit. It is shown that the effective soft-switching operation region and its efficiency improvement result on the basis of experimental evaluations.
