31.
A thyristor circuit is feeding an R-L load. The turn on time can be reduced by
32.
A single phase semiconverter is supplying RLE load and has a freewheeling diode across the load. The firing angle is a. The freewheeling diode conducts for
33.
In a full bridge inverter fed by a battery of voltage V, the rms value of fundamental component of output voltage is
34.
In a single phase full wave regulator feeding a resistive load, the average current over one full cycle
35.
Two single phase semi-converters are connected in series to form a series converter. The input is v = Vm sin ωt and a1, a2 are the firing angles. If a1 = 0, the dc output voltage is
