Find VYB, when T6, T1 and T2 are conducting. Consider a star connected R load. Correct Answer 0

When 6, 1 and 2 are conducting and the others are off. They conducting SCRs can be represented as closed switches. The load terminals Y and B are connected to the negative bus but the terminal R is connected to the positive bus. Supply voltage is Vs. VYN = VBN = -Vs/3. VYB = VYN – VBN = (-Vs/3) – (-Vs/3) = -Vs/3 + Vs/3 = 0.
