Hello,

can anyone tell me where am I wrong please:

we have:

the firing angle of Thyristors=120°, E=100v, V(t)=220sin(angle), f=50hz, , R=10ohm, dissipation angle = 90°

I want to know Uc(angle), for me I have found:

120°+a -->180°-a° Uc=V(t)

180°-a°-->270°-a° Uc=0

270°-a-->300°+a Uc=E

300°+a-->360°-a Uc = -V(t)

360°-a-->450°-a Uc=0

450°-a-->480°+a Uc=E

wtih a = sin^-1(E/Vm)
