What Is The Difference Between On-off Control And Phase Control?

1.	What Is The Difference Between On-off Control And Phase Control?
Answer» ON-OFF control: In this method, the THYRISTORS are employed as switches to connect the LOAD circuit to the source for a few CYCLES of the load voltage and disconnect it for another few cycles. PHASE control: In this method, thyristor switches connect the load to the ac source for a portion of each half cycle of INPUT voltage. ON-OFF control: In this method, the thyristors are employed as switches to connect the load circuit to the source for a few cycles of the load voltage and disconnect it for another few cycles. Phase control: In this method, thyristor switches connect the load to the ac source for a portion of each half cycle of input voltage.
