SiC soft- switched dc - ac converter for high frequency application

Abstract

With the advancements in power electronics and semiconductor technologies, there has been a high improvement in the performance of the electronics systems and devices. In order to make the system compact, the number of components used should be less. When the device has to be used for high frequency applications, the switching losses increases and efficiency of the system reduces. Therefore, the emerging semiconductor Silicon Carbide is made use to operate at higher frequencies in the range of Mega Hertz. To further reduce the switching losses, soft switching technique is implemented. Also, to minimize the number of components used and the cost, a single inductor multi output dc - ac converter is employed. In this paper, a comparative analysis of the silicon and silicon carbide devices in a mutli - output dc - ac soft switched converter is performed using MATLAB/SIMULINK.
