摘要： Provided is a regenerative switched reluctance motor driving system which allows a motor to have a reduced size and weight and an increased efficiency as well as improved energy recovery efficiency at the time of regenerative braking without using a neodymium magnet. Based on an angular position of a rotor in the motor, a constant current flip-flop circuit 2 renders two current paths alternately conductive so as to allow a rectangular-wave current having a width of an electrical angle of 180° to alternately flow in two coils in the motor 3, and shifts the timing of rendering the two current paths alternately conductive, between when driving and when braking the motor 3, by a time during which the rotor is rotated by an angle corresponding to an electrical angle of 180°. When driving the motor, a DC constant current power supply unit 1 discharges a DC power supply, while when braking the motor, it receives an input current through a negative terminal of the DC power supply, and outputs a DC current to the constant current flip-flop circuit 2, and further outputs a DC current regenerated from the motor 3 through the constant current flip-flop circuit 2 to a positive terminal of, and thereby charges, the DC power supply.
