Abstract: PURPOSE: A soft start device and a method thereof are provided to prevent the voltage drop of a power supply device by using a contactless power device with a Y-connection state. CONSTITUTION: One side junction part(304a) of a first on/off state switch(304) is connected to the output terminal of a three-phase induction motor(303). One side junction part(305a) of a second on/off state switch(305) is connected to the output terminal of the three-phase induction motor. A contactless power device(302) supplies a voltage to the induction motor and softly starts the motor. A control part(301) outputs a control signal for a Y-connection to the first on/off state switch. The control part outputs a control signal for a delta connection to the second on/off state switch.
