Question

Calculate the value of the Input power factor using the data: Fundamental displacement factor=.96, Distortion factor=.97.

(a) .93

(b) .84

(c) .48

(d) .89

This question was posed to me during an interview.

The query is from Solid-State Switching Circuits topic in division Introduction to Solid-State Switching Circuits of Electric Drives

Answer 1

Right choice is (a) .93

To elaborate: The value of the input power factor is a product of the (Fundamental displacement factor)×(Distortion factor)=g×F.D.F=.97×.96=.93.
