摘要

The single-phase matrix converter applied to the contaedess electrical power transfer system is introduced.Con-sidering special request of the contactless electrical power transfer system, the principle of the single-phase matrix convert-er is analyzed.In view of the whole system constitution based on single-phase matrix converter, the design of electric circuit is proposed,and a stand-alone prototype of the system is completed.Then the experimental issues of each part are dis-eussed,including energy transfer situation of the overall system.The results indicate that this system has an excellent ener-gy transfer characteristics and its power factor is approximate to unity.Accordingly,it ean be concluded that the single-phase matrix converter possesses a wider foreground in the domain of eontactless electrical power transfer system.%将单相矩阵变换器(Matrix Converter,简称MC)应用到非接触式电能传输系统中,结合非接触式电能传输技术中的特殊要求,埘单相MC工作过程进行了民深入分析,给出了系统的电路设计,进而实现了一套独立的样机.在此基础上,对滤波、输入输出特性等关键环节进行了实验分析,并对整个系统的电能传输情况进行了测试.实验结果表明,该系统不仅可以使输入功率因数接近1,而且减少中问环节的能量损耗,增大耦合器的能量传输密度,从而证明了单相MC应用于非接触式电能传输系统的可行性和优越性.
