Abstract
The rapid growth in renewable energy based electric power generation continuously pushes for the need of high performance power conversion systems. This paper mainly focuses on the design and performance study of a DC– DC ZETA converter using wide bandgap power devices. The converter is designed based on a SiC MOSFET/SiC Schottky diode, and its performance is compared with a Si IGBT/SiC Schottky diode based converter. The switching characteristics of the SiC MOSFET and Si IGBT power devices within the converter are studied and compared. A comprehensive evaluation of the total power loss and overall efficiency of the converter is analyzed and reported. The results indicate that the converter with the SiC MOSFET/SiC Schottky diode has great potential to work efficiently under different operating conditions.
