| 摘 要： | 为使BSPWM控制逆变器具有较好的正弦输出波形,对BSPWM逆变器的输出信号进行谐波分析,针对在载波比为N、调制比M〈1的条件下具有无低于N-2阶谐波的特点,设计了一无源LC滤波网络。文中给出了滤波器参数的计算方法。给出的数值算例,可使总谐波畸变为0.14%,远小于1%,显示了该滤波网络的优越性及方法的有效性。

| Abstract: | To make the BSPWM-control inverter be of a good sine wave output, by harmonic analyzing to its output voltage, and taking the converter characteristic of none low-harmonic that less than N-2, which is under the existing conditions of carry wave ratio N and the modulation ratio M〈1, a L-C filtration network is put forward in the article. Furthermore, the parameter calculation method of the filter is proposed. The example shows that the THD is 0.14%, far less than 1%, and the filtration network is superior and efficacious. |
