A regenerative brake control system for controlling an armature current of DC motor by on-off operation of a chopper through resistor means which is connected in series with the DC motor and is appropriately divided into sections is disclosed. In the system, the notching operation of the resistor means is controlled in such a manner that the duty cycle of the chopper immediately following the short-circuiting of one section of the resistor means is to be the minimum value tolerable to the chopper. |
