Working Principle of Soft Starter

The soft starter uses a three-phase parallel thyristor as a voltage regulator, which is connected between the power supply and the motor stator. Such a circuit is a three-phase fully controlled bridge rectifier circuit.

When the 3-phase soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully turned on. The motor works according to the mechanical characteristics of the rated voltage to achieve a smooth start, reduce the start current, and avoid over-current tripping.

When the motor achieves the rated RPM, the start-up process ends, and the soft starter automatically replaces the thyristor that has completed the task with a bypass contactor to provide the rated voltage for the normal operation of the motor, thereby reducing the heat loss of the thyristor and prolonging the service life of soft starter, enhancing its working efficiency, and preventing the grid from harmonic pollution.

The motor soft starter also provides a soft stop function. The soft stop is the opposite of the soft start. The voltage gradually decreases and the revolutions gradually drop to zero to avoid the torque impact caused by the free stop.
