摘　　要：根据单端反激变换器的电路和工作波形,推导了其在输出电流连续和不连续情况的工作原理,并且给出了在MATLAB/Simulink中的正激变换器的仿真模型和仿真结果。通过对仿真结果的分析得出以下结论:其优点是电路所用元器件少,电路简洁。其缺点如下:输出功率较小,稳定性较差,以及开关应力大,电路能量损耗较大。According to the circuit and waveforms of single end flyback converter, the output current is derived in the case of continuous and discontinuous work principle, and the simulation model and simulation results of forward converter in MATLAB/Simulink are given. Through the analysis of the simulation results, the following conclusions are drawn： the advantages of the circuit are less components and simple circuit. The disadvantages are as follows.＂ the output power is small, the stability is poor, and the switch stress is large, and the energy consumption of the circuit is large.
