A single-phase half-wave thyristor circuit with R load is triggered at an angle of = 0 . As such, the maximum value of the average output voltage would be given byConsider Vs = Vm sin t.

For a single phase thyristor circuit with R load &amp; firing angle , the conduction angle can be given by

In a single phase half-wave thyristor circuit with R load &amp; Vs=Vm sin t, the maximum value of the load current can be given by

In the method of phase control, the phase relationship between ___ &amp; ___ is controlled by varying the firing angle

The average output voltage is maximum when SCR is triggered at t =

A voltage source Vs = Vm sin t is connected in series with a resistance R and an SCR. At some firing angle delay of a positive gate pulse is applied to the SCR which turns on the SCR. Considering ideal conditions, at the instant the voltage at the resistor terminals Vo
