Physics · Power Electronics Drives
A separately excited DC motor is fed from a single-phase AC to DC full-wave fully controlled converter. The motor runs at its rated speed when the firing angle of the converter is zero. Assuming continuous conduction, to reduce the speed of the drive to half of its rated speed with the same load torque, the firing angle should be adjusted to approximately:
