Abstract

PURPOSE: To provide an operation control system for elevator, in which a self-resetting breaking element is connected in series to semiconductor elements adapted for controlling an elevator driving DC motor, so as to protect said semiconductor elements from short-circuit current that is caused when power supply is interrupted during regenerative operation of the DC motor.
