利用Matlab中的simulink工具箱仿真。单相桥式PWM逆变电路，采用单极性触发方式，负载 ，电源 ，建立模型，制作PWM触发模块，画出基波幅值与占空比关系图。-Using simulink toolbox of Matlab simulation. Single-phase PWM bridge inverter circuit, the use of unipolar trigger mode, load, power, establishment of model, trigger

建立了单相H桥逆变器单极性PWM调制仿真模型，运行效果良好(A unipolar PWM modulation simulation model of single-phase H bridge inverter is established, and the running effect is good)

PWM单极性 simulink 模型, 管子1和3互补导通，管子1和4互补导通，搭建的模型，大家可以试试(PWM single polar simulink model)
