| Abstract: | The paper addresses itself to the issue that both the starting performance and the adjusting speed capability of asynchronous motor have been improved after applying the frequency conversion technology, and so the application of asynchronous motor is further developed. The technology of SPWM is the key to make the voltage and frequency of the alternating output of the frequency converter to be adjustable. |
