Question

The below shown rectifier configuration has continues load current, find the expression for the average value of output voltage when the supply Vs = Vm sinωt is connected.

(a) (Vm/π)cosα

(b) (2Vm/π)cosα

(c) (Vm/π) (1+cosα)

(d) (2Vm/π) (1+cosα)

I got this question in unit test.

My question is taken from Single Phase FW AC-DC-3 topic in portion Converters of Power Electronics

Answer 1

Correct answer is (b) (2Vm/π)cosα

Explanation: Vo = 1/π x [∫ Vm sinωt d(ωt)] Where the integration runs from α to π+α.
