Abstract

In this article, a soft-switched structure for the synchronous buck converters is proposed and analyzed. In this structure, by adding an LC circuit to the synchronous buck converter, soft-switching condition performance is obtained. Both the main and synchronous power switches turn on and turn off under ZVS condition. Therefore, the switching losses are eliminated completely and high power efficiencies can be obtained by implementing the proposed converter. In this article, the proposed structure and its operational modes are investigated in details. The proposed converter is compared with other soft-switched synchronous converters and the results are investigated comprehensively. The efficiency of the proposed converter is obtained and compared to the hard-switched converter. In addition, in order to validate the desired operation of the proposed structure, a 200W sample of this converter is simulated in the PSCAD software and the achieved results are analyzed in details.
