Claims

[Scope of utility model registration request]

a first transistor that produces a speed control output of the AC electric motor; and a second transistor that controls the output operation of the first transistor.
The structure includes a charge/discharge type timer member that sets a time until the dynamic voltage of the AC electric motor reaches the AC power supply voltage, and the driving power source for the first transistor is supplied via the timer member. a first switch member that applies voltage to a second transistor and operates on and off in conjunction with a power operation switch of the motor;
a second switch member that is turned off in succession after the first switch member is turned off; the input stage of the timer member is connected to the first switch member, and the output stage of the timer member is connected to the second switch member. What is claimed is: 1. A power supply device for an AC electric motor, characterized in that it is configured to perform cut-off control.
