A single-phase voltage controller has input of 180 V, 50 Hz and a load . For five cycle ON and three cycle OFF. Find the load power?

For the given circuit, what is the range of firing angle for which, output voltage is not controlled.

A 1-ϕ Full wave AC voltage controller feeds a load of R = 10 Ω with an input voltage of 220 V, 50 Hz. Firing angle for both the thyristor is 60°. Calculate the RMS value of current across thyristor (in A).

A 60 Hz, Single phase full wave AC Voltage controller feeds an RL load. The load is having the R = 6 Ω and L = 16 mH. The output is fully controllable for the range of ‘α’ (firing angle) is
