Two single phase semi-converters are connected in series to form a series converter.

The input is v = V_{m} sin ωt and α_{1}, α_{2} are the firing angles.

If α_{1} = 0, the dc output voltage is

A. V_{m} / π (1 + cos α_{2})

B. V_{m} / π (2 + cos α_{2})

C. V_{m} / π (3 + cos α_{2})

D. V_{m} / π (4 + cos α_{2})
