Abstract
In order to effect regenerative brake control from a high speed with a chopper, a resistor is inserted in a motor circuit. The duty cycle of the chopper is reduced before the resistor being shorted, thereby dampening the increase of the voltage across a filtering capacitor which otherwise might occur at the time of the resistor being shorted.
