摘要
首先介绍了PWM控制技术的基本原理,然后结合无源逆变器,详细地阐述了桥式直流PWM变换器的工作原理。最后在MATLAB/Simulink建立了桥式直流PWM变换器的仿真模型,然后对仿真结果进行了分析,仿真结果表明通过调节占空比,可以改变电压和电流的大小和方向,与理论分析完全一致。
The paper firstly introduces the basic principle of PWM control technology, and then combines with passive inverter, and also expounds in detail the working principle of PWM bridge DC converter. Finally, the simulation model is built in the MATLAB/Simulink of bridge DC PWM converter, and then the simulation results have been carried on the analysis. The simulation results show that the size and the direction of the voltage and current can be changed by adjusting the duty ratio, and it is fully consistent with the theoretical analysis.
