Dual-output step-down soft switching current-fed full-bridge DC-DC converter

In this paper, a dual-output step-down soft-switching current-fed full-bridge dc-dc converter is proposed. The proposed converter is able to provide two independent outputs. In this topology, zero current switching of primary-side devices and zero voltage switching of secondary-side devices are obtained. In this paper, the proposed converter is analyzed with complete details and all equations of voltage and current of all components are extracted. Moreover, the required conditions for soft switching of switches are calculated. Finally, the performance of the proposed dc-dc converter is reconfirmed by simulation results provided by EMTDC/PSCAD software.
