| 摘 要： | 分析单相PWM整流电路的结构、工作原理和控制方法,通过选择适当的工作模式和工作时序,可使PWM整流电路输出直流电压稳定。将正弦脉宽调制技术应用于PWM整流电路,使其交流侧输入电流非常接近正弦波,且与输入电压同相位。同时调节交流侧电流的大小和相位,使能量在交流侧和直流侧双向流动。在建立基于Simu-link7.6的仿真模型基础上,通过分析PWM整流电路各处电压、电流波形,验证其控制方法及仿真设计的正确性。

| Abstract: | The article analyzes the structure,working principle,and control method of single-phase PWM rectifier circuit.Through the selection of appropriate working mode and time sequence,PWM rectifier circuit can generate stable DC voltage.The sine pulse width modulation technology is applied in PWM rectifier circuit to make the output current at the AC side extremely close to the sine wave and at the same phase with input voltage.Meanwhile,the adjustment of the value and phase of the current at the AC side can enable the bi-directional flow of energy between the AC side and DC side.On the basis of Simulink7.6 emulated model and through the analysis of voltage and current wave at each points of PWM rectifier circuit,the article verifies the correctness of the control method and emulated design. |
