ACTIVE AND PASSIVE SNUBBER-ASSISTED SOFT-SWITCHING FOR BIDIRECTIONAL ISOLATED FULL-BRIDGE DC–DC CONVERTERS

Abstract

This paper introduces a nine-fold direct current-direct current converter that features bidirectional isolation and gentle switching to continuously charge and discharge batteries.   The converter employs two passive capacitor diode snubbers and an active flyback to facilitate gentle switching with reduced voltage and current. This mitigates stresses and surges.   The investigation commences with a concise explanation of the converter's operation, followed by an analysis and enhancement of the electronic device.
