Consider a full-wave, single-phase controlled rectifier, similar to that shown in Figure 12.2, that is used to drive a DC motor instead of the resistive load Ro. Assume that the motor is rated at 4 kW and 110Vrms and that the AC supply is 80Vrms 60 Hz. Also assume that the motor inductance is very large such that the motor current is ripple-free and that the motor constant is 0.055 V/rpm. If the motor runs at 1,000 rpm at rated current:
Find:
a) Determine the firing angle of the converter.
b) Determine the rms value of the supply current.
