Evaluation of SiC MOSFET in Buck converter

摘要

SiC device technology has gained much progress. However the advantages of the device level have not been clearly shown in a power conversion circuit. The purpose of this work is to apply the SiC device in a Buck converter and to evaluate the MOSFETs' driving performance and switching losses for high switching frequency operation. The analysis is verified by the design and test results for a high frequency hard switching silicon carbide based Buck converter.
