Find the expression for average output voltage for the given circuit if firing angle is greater than 30°. Take Vmp = secondary side maximum value of phase voltage. . d) (3√3Vmp/2π) x . Correct Answer (3√3Vmp/2π) x [1+cos(30+α)

Vo = 3 x Where, the integration runs from α+π/6 to π. Because conduction takes place from 30 + α to 180° for T1 and than the waveform is symmetrical for all other SCRs. Vo = (3√3/2π) x Vmp x .
