Question

What is the distortion factor value in CSI?

(a) .85

(b) .90

(c) .95

(d) .88

I had been asked this question in final exam.

I want to ask this question from Solid-State Switching Circuits topic in chapter Introduction to Solid-State Switching Circuits of Electric Drives

Answer 1

The correct answer is (b) .90

For explanation I would say: The distortion value in CSI is .90. The r.m.s value of the fundamental current is 2√2I÷π and r.m.s value of the output current is I. The distortion factor is (2√2I÷π)÷I = .90.
