Question

In a single phase full converter with resistive load and firing angle α, the load current is

(a) zero at α, π+α, …

(b) remains zero for duration α

(c) Vm/R sinα at α, π+α, …

(d) remains zero for duration π-α

The question was asked during an interview.

I'm obligated to ask this question of Single Phase FW AC-DC-5 in section Converters of Power Electronics

Answer 1

Right option is (c) Vm/R sinα at α, π+α, …

To explain I would say: The current starts to flow from α, π+α, …
