Question

In a B-2 type full controlled bridge converter

(a) one SCR conducts at a time

(b) two SCRs conduct at a time

(c) three SCRs conduct at a time

(d) four SCRs conduct at a time

I had been asked this question in final exam.

Enquiry is from Single Phase FW AC-DC-1 topic in section Converters of Power Electronics

Answer 1

Right option is (b) two SCRs conduct at a time

The best I can explain: B-2 is the bridge type controller, in which 2 devices conduct at a time. One acting as the current supplying path and other acts as a return path.
