摘　　要：研究了隔离型半桥变换器,首先阐述其工作原理,并且给出了其在MATLAB/Simulink中的仿真模型和仿真结果,仿真结果与理论分析完全一致。而且通过仿真分析得出带隔离变压器的半桥电路可以实现直流变直流的目的,相对于直流斩波电路,其更不容易发生变压器的偏磁和直流磁饱和。The isolated-half bridge converter is studied. Firstly, the working principle is described, and its simulation model and simulation results based on MATLAB/Simulink are given. The simulation results are in good agreement with the theoretical analysis. Moreover, through simulation analysis, it can be concluded that the half-bridge circuit with isolated transformer can realize DC to DC conversion. Compared with the DC chopper circuit, it is less prone to transformer bias and direct current saturation.
