Abstract

PURPOSE: To prevent the erroneous detection due to the charge of a commutation capacitor by an electromagnetic-switch actuation detecting circuit, by discharging the commutation capacitor before an electromagnetic starting switch is actuated.
CONSTITUTION: A starting switch 10 is switched to a normally open contact b at starting, and a forward-backward switch 11 is switched to a normally open contact b or e. Since the output of an operation amplifier 13x is a 1, a thyristor 14d of a commutation capacitor discharge circuit 14 is triggered, and the commutation capacitor 4d is discharged. Then, the potential at the negative input terminal of an operation amplifier 6g is decreased, and the output of the operation amplifier 6g is inverted. At this time, a capacitor 13q is charged via a resistor 13l. After a specified time, the output of the operation amplifier 13x is inverted from a 1 to a 0, a transistor 13n is conducted, an electromagnetic starting switch 2 or 3 is actuated, thereby an electric car is started.
