Abstract

PURPOSE: To obtain necessary braking force by flowing an electric current through the specific two phases of the three-phase winding of a squirrel-cage induction motor in a predetermined direction when a regenerative braking fails, thereby dynamically braking an electric motor vehicle.
CONSTITUTION: If a regenerative braking fails due to the lack of a driven vehicle at a DC trolley wire side when the rotating energy of a squirrelcage induction motor 7a is regenerated through a PWM inverter 6 at the DC trolley wire side to allow the vehicle to regeneratively brake, the regenerative brake is stopped and reverse conducing thyristors 6UW6Z constructing the PWM inverter 6 are controlled to supply a direct current to the two phases of the motor 7a. Thus, the motor 7a is dynamically braked with the direct current. In this manner the dynamic braking can be performed without adding a specific main circuit configuration when the regenerative braking fails in the vehicle.
