摘要 PWM 逆变器在应用中产生的共模电压将影响系统的可靠运行。文中研究了电压源型PWM 变频器产生的共模电压及其负面效应产生机理,揭示了共模电压产生的原因及其抑制方法,并得出共模电压是变频器输出负面效应产生的主要根源的结论,为滤波器的设计提供理论依据。根据共模电压是由一系列高频谐波组成这一特性,提出了一种新颖的逆变器输出前馈有源滤波器结构,可有效地消除了变频器输出共模电压的负面效应,实验验证了这种结构的有效性。 Pulse width modulated (PWM) inverter can generate common-mode voltage which will decrease system reliability. Common-mode voltage generated by voltage source PWM inverter and the essences of its adverse effects are investigated in the paper, and common-mode voltage reducing methods are also presented. Ac-cording to the high frequency characteristic of common-mode voltage, a novel inverter output feed forward active filter is proposed that has low-pass characteristic and is suitable for reducing common-mode voltage and its adverse effects. Experiments are used for identifying its effectiveness.
