摘　　要：根据新型高频链SPWPM变换器的工作原理,建立了SPWPM逆变环节和周波变换环节的数学模型。对两个环节的输出波形进行了数学分析,得到了输出电压波形的解析表达式,揭示了它们的频谱特征。从理论上证明了“SPWPM波包含了SPWM波的全部信息,而不含调制波(基波)频率成分”的结论,及变换器高频链原理的正确性。分析表明该变换器设计思想新颖,易于实现。仿真和实验证明了理论分析是正确的,为深入研究该变换器提供了理论依据。According to the operational principle of the novel HF-LINK SPWPM converter, the mathematical models of the SPWPM inverter stage and the cyclconverter stage are established. With mathematic analyzes to the two exportations of the links, the expresses type of the exportation electric voltage is gained, and their frequency characteristic is revealed. The conclusion is theoretically proved that the transformation of SPWPM includes all information of SPWM wave, but does not contain the frequency of modulating wave, and the accuracy of the high-frequency-link principle. The analysis shows that the converter has a novel design, and is apt to realization. Simulation and experiment certify that the theories analysis is right, which provides theories for further study according to the converter.
