Control principle of soft Starter

Soft starters through control of thyristor conduction angle to control the output voltage. Therefore,

Soft Starter is in essence a step-down starter capable of automatic control, the ability to adjust the output voltage, current loop control, than traditional blood pressure start mode (such as series resistance starting, autotransformer starting, and so on) have more advantages. Such as the full load start the fan and water pump, variable torque loads, the motor soft stop, pump can completely eliminate water hammer effects.
