摘要
研究了一种采用闭环控制的逆变系统。该系统以单相全桥电压型逆变电路作为被控对象,将逆变电压瞬时值输出作为反馈,构成电压PI控制的单闭环结构。建立了逆变系统的主电路和控制电路Saber仿真模型,并对比分析了不同PI参数控制下的逆变输出电压和给定电压仿真波形。仿真实验结果表明:PI控制对逆变系统具有很好的控制效果。
In order to make the control flexibility and anti‐interference ability of PWM inverter circuit better ,an inverter system with the closed‐loop control is proposed .The system ,in which the single‐phase full‐bridge voltage inverter source inverter is regarded as the controlled object ,has the single closed‐loop structure with PI control by feeding the instantaneous output voltage of the inverter .The main circuit model and control circuit model of the inverter system are built upon Saber .The waveforms of the inverter output voltage are compared with those of given voltage under different PI parameters .
