ABSTRACT:
A driving circuit for improving starting of a hybrid induction motor and its method includes a capacitor for operation electrically connected between a main coil and a auxiliary-coil, and a starting and current cutting-off means electrically connected with the capacitor for operation, applying a high starting current to a motor in starting, and cutting off the starting current when the motor is operated at a synchronous speed after the starting, so that a satisfactory starting characteristic can be obtained by increasing output under a low voltage state in starting, and effective operation can be performed by decreasing output under a normal operation state after the starting is completed.
