Question

Calculate the average value of diode current in 1-Φ Full wave semi-converter for the load (Highly inductive) current=5.2 A and α=11°. (F.D configuration)

(a) .32 A

(b) .31 A

(c) .25 A

(d) .27 A

This question was posed to me during an interview.

My query is from Solid-State Switching Circuits topic in chapter Introduction to Solid-State Switching Circuits of Electric Drives

Answer 1

The correct option is (b) .31 A

Best explanation: The average value of diode current in 1-Φ Full wave semi-converter is Io(α÷π). It is the average value of the diode current. Iavg= Io(α÷π)=5.2(.061)=.31 A.
