Design and Analysis on Wireless Power Transfer System Based on SiC

采用传统Si材料半导体器件和附有高频逆变器的无线电能传输系统,存在热稳定性差、导电性能较差和介电常数较大等问题。为此,研究一种基于SiC器件的无线电传输系统,从工作频率、高频逆变、整流、补偿拓扑几方面对基于SiC的无线电能传输系统进行结构和参数设计,并根据设计的系统结构和参数,用PSpice仿真软件搭建基于SiC和Si的WPT系统模型进行对比,验证了将SiC材料应用于WPT系统中对整个系统的性能带来的优良性。

The wireless power transfer （WPT） system using traditional semiconductor apparatus made of Si materials and the high-frequent inverter has some problems such as bad thermal stability, bad conductivity performance and larger dielectric constant, therefore, the paper aims to study a kind of wireless power transfer system based on SiC apparatus. In aspects of working frequency, high-frequent inverter, rectification and compensation topology, it designs structure and parameters of the system and then adopts PSpice simulating software to build the WPT system model based on SiC. By comparing this new model with the model based on Si, it verifies superiority of applying SiC materials in the WPT system.
