| 中文摘要: |
| 利用双极性SPWM正弦脉宽调制技术实现单相异步电动机变频调速。在MATLAB/Simlink软件中建立双极性SPWM控制器、主电路中的整流和逆变电路。从仿真结果中可以看出,在未加滤波器之前,单相异步电动机变频调速性能较差和逆变器输出电流畸变程度大。加滤波器后,滤除高次谐波,提高电动机调速性能和逆变器输出电流更接近正弦波。 |
| 英文摘要: |
| Variable frequency speed control of single-phase asynchronous motors is realized through bipolar SPWM. A bipolar SPWM controller and a rectification and inverter circuit of the main circuitry are established in the MATLAB/Simulink. As shown in the simulation results, the single-phase asynchronous motor has a poor variable frequency speed control and the inverter output current has serious distortion before the addition of the filter, and application of the filter removes higher harmonics, improves motor’s speed control, and makes inverter output current more similar to the sine wave. |
