摘　　要：在对桥式可逆斩波电路作出理论分析的基础上,建立基于MATLAB/Simulink/Power System工具箱的桥式可逆斩波电路的仿真模型,给出了电阻电感性负载及电动机负载时的仿真结果,并对其进行分析,同时也验证了所建模型的正确性。The theory of reversible bridge chopper circuit is introduced. A technique is presented in setting up the models based on MATLAB/Simulink/Power System software, and the voltage and current timing waveforms support this technique. The simulation results of the electric circuit with resistance -inductance load or motor load are also presented. At last, the models of this full - bridge DC/DC converter circuit are proved correct.
