Abstract

PURPOSE: To restrain voltage increase of a filter condenser and also control phases of on-pulse and off-pulse so that a circulating ratio of a chopper is not increased, by inserting a resistor.
CONSTITUTION: Regeneration braking is effected by adjusting a current of a motor A with a chopper CH. When the regeneration load is lost and a terminal voltage of a filter condenser is incresded, a voltage detector VD detects it and renders a thyristor OVTh conductive, and thereby, a resistance R which protects the condenser is inserted. A gate controller GA controls phases of on-pulse and off-pulse for the chopper so that an armature current IA is not increased, that means, the equivalent value of the chopper CH is not decreased.
