| Principle | The reactance is connected in series in the stator circuit of the motor, and the starting multiple control of the current is realized by sharing the voltage at the motor end. |
Parallel thyristors are connected in series in the stator circuit of the motor, and the conduction angle of the thyristor is adjusted through the closed-loop control system to gradually increase the motor terminal voltage and realize the starting of the motor. | |
