Electrical Drive Circuit For A Variable-Speed Switched Reluctance Motor An electrical drive circuit for a variable-speed switched reluctance motor having a bifilar winding is provided. First, second, and third thyristor switches each having respective firing circuits are associated with the motor. A commutation capacitor device is associated with one of the thyristor switches. A sensing means determines the direction of current flow through the commutation capacitor device, and a control system prevents the first and third thyristor switches from conducting when the second thyristor switch is conducting and prevents the first and second thyristor switches from conducting when the third thyristor switch is conducting. |
