Explain series switching control of AC load.
Description : Explain the pulse width modulation technique for control of AC output voltage.
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.
Answer : Series capacitors on transmission lines are of little use when the load VAR requirement is small.
Description : Why dc series motor should not be started at no load?
Description : Explain switching model of MOSFET.
