| 摘 要： | 分析了双脉宽调制(PWM)变频器的工作原理与运行特性,在此基础上针对其直流电压易出现波动的缺点,提出了一种新型的带有电流前馈的双PWM变频器一体化控制策略.该控制策略将逆变器负载的动态特性整合在PWM整流器的电流控制当中,加速了整流器和逆变器之间的电流平衡,减轻了直流环节滤波电解电容器的负担,稳定了直流母线电压.系统仿真结果表明该方案正确、有效.

| Abstract: | The operation principle and the running characteristic of dual-PWM inverter were analyzed.On this base,because the DC bus voltage was easily fluctuated,a new integration control strategy for dual-PWM inverter with current feedforward was proposed.It put dynamic characteristics of load into the PWM rectifier's voltage control which accelerated the current balance between rectifier and inverter,reduced the burden of DC bus capacitor and stabilized the DC bus voltage.The simulation results verified the suggest... |
