Question

A single-phase semi-converter is connected to a 230 V source and is feeding a load R = 10 Ω in series with a large inductance that makes the load current ripple free. Find the average output current for α = 45°.

(a) 14 A

(b) 17 A

(c) 10 A

(d) 0 A

The question was posed to me in an international level competition.

My question is from Single Phase Semi-Converters-2 topic in chapter Converters of Power Electronics

Answer 1

Right answer is (b) 17 A

Explanation: Vo =( Vm/π) (1 + cosα)

Io = Vo/R.
