Description : Explain the principle of ON-OFF control and phase control of AC voltage controller with suitable circuit and waveforms.
Answer : The integral cycle control (on-off control) and phase angle control are the two types of AC voltage controller. The principle of ON-OFF control: The on-off control is also called an integral cycle ... control. In phase control, the switch is on for some period of each cycle.
