| Abstract: | The main circuit and principle of rotor-side variable frequency drive system is proposed firstly. At the same time, its advantage is given. Because the PWM converter technique is adopt, the power factor is increased and the harmonic is little. The mathematical model and control strategy in rotary coordinate is gained. Finally, the experiment and conclusion are given. |
