On a PCM-controlled AC generator, system voltage is controlled by varying the _____ of the current applied to the field coil.
A)frequency
B)duty cycle
C)bandwidth
D)amplitude

Question

Quizplus · Accepted Answer

The system voltage in a PCM-controlled AC generator is controlled by varying the duty cycle of the current applied to the field coil. This approach adjusts the average power delivered to the field coil, thereby controlling the magnetic field strength and ultimately the output voltage of the generator.
