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

[A]. (1 + cos a2)
[B]. (2 + cos a2)
[C]. (3 + cos a2)
[D]. (4 + cos a2)

Answer: Option C

Vdc= Vdc1 + Vdc2.
=(Vm/π)(cos(a1)+1) + (Vm/π)(cos(a2)+1),
=(Vm/π)(cos(0)+1) + (Vm/π)(cos(a2)+1),
=(2Vm/π)+(Vm/π)(cosa2+1),
=(Vm/π)(2+(cosa2+1)).
=(Vm/π)(3+cosa2).
