摘　　要： 应用脉冲波形积分法对串（并）联谐振型变流器进行小信号建模分析。在建模中，通过周期性脉冲函数将变流器的各个子拓扑等效成一个拓扑，并对小信号采样函数进行拉氏变换；同时根据变流器的不同类型作出相应的近似处理。最后，将计算机仿真数据与实测数据进行了对照比较。 A novel approach to modelin8 resonant conventers, was presented in this paper.The variant subtopologies of a converfer are unified into an equiualent topology by the periodicpulse functions;Laplace transforms of the sampled function ,insteady of continuous ,of a small sig-nal variable are made;furthermore,the linear approximation is processed according to the differenttypes of converters, The conventional series and parallel converters are used as examples to discussthe principles of the approach. Finally the computer calcultion data is compared with the experiment results to con firm the models to be correct.
