摘　　要：介绍了集成输入滤波电感和倍流电感的推挽正激变换器。这种变换器具有平滑的输入电流,简单的主电路,小的体积,高的效率和功率密度。分析了它的工作过程,对于磁集成部分给出了Z参数模型,并利用该模型,对变换器进行了PSPICE仿真。最后通过试验验证了仿真结果。A push-pull forward converter with input filter inductor and current douhler output inductor is proposed. The converter can get smooth input current, and it's main circuit is simple. The converter can be made small, the efficiency and power density can be high. The operation process of the converter is analyzed. The Z-parameter two-port net work model of the integrated magnetics is proposed. At the same time the converter with the model is simulatied by PSPICE. At last the result of the simulation is proved with experiment.
