A single phase full converter delivers power to a resistive load R. For an AC source voltage of Vs, the average output voltage Vo is given by (where α is firing angle):
1
\(\rm\frac{\sqrt{2} v_s}{\pi}\)(1 − cos α)
2
\(\rm\frac{\sqrt{2} V_s}{\pi}\)(1 + cos α)
3
\(\rm\frac{\sqrt{2} V_s}{\pi}\)(1 + sin α)
4
\(\rm\frac{\sqrt{2} v_s}{\pi}\)(1 − sin α)
