本文提出了一种利用虚电阻抑制PWM逆变器输出LC滤波器瞬态振荡的方法。虚拟电阻是一种额外的控制算法，它模拟了输出LC滤波器中电阻的作用。因为没有使用真正的电阻，振荡可以有效地抑制而不牺牲功率效率。虚拟电阻的实现取决于电阻如何连接到LC滤波器。实验结果验证了所提出的方法。
This paper presents a method to damp transient oscillations on the output LC filter of PWM inverters by using a virtual resistor. A virtual resistor is an additional control algorithm that simulates the roles of a resistor in the output LC filters. Because no real resistor is used, the oscillations can be damped effectively without sacrificing the power efficiency. The implementation of the virtual resistor is determined by how the resistor is connected to the LC filter. Experimental results are included to verify the proposed method.
