ELECTRONIC SUPPLY ARRANGEMENT FOR A SERIES DC MOTOR WHICH PERMITS RAPID TRANSITION BETWEEN DRIVING AND REGENERATIVE BREAKING

摘要

The circuit effects a changeover from the traction configuration to the braking configuration or vice-versa in less than one millisecond. It includes the field winding (3) of the motor (1) disposed between a traction thyristor (12) and a main chopper (13) followed by a traction diode (14) and the armature of the motor, the field winding being in parallel with a free-wheeling diode (D5) and a shunt thyristor (THS).
