Calculate the r.m.s value of thyristor current in 3-Φ Full wave converter for the load current=2 A and α=59°.(a) 1.15 A(b) 2.55 A(c) 2.07 A(d) 2.89 AThe question was asked during an interview.This question is from Solid-State Switching Circuits in chapter Introduction to Solid-State Switching Circuits of Electric Drives

Answer» RIGHT choice is (a) 1.15 A

The explanation is: The r.m.s value of THYRISTOR CURRENT in 3-Φ Full WAVE converter is Io√1÷3. It is the r.m.s value of the thyristor current. I(r.m.s) = Io√1÷3=1.15 A.
