Question

Calculate the average value of diode current in 1-Φ Full wave semi-converter for the load (Highly inductive) current=75.2 A and α=41°. (Asymmetrical configuration)

(a) 46.16 A

(b) 42.15 A

(c) 41.78 A

(d) 41.18 A

This question was posed to me in my homework.

Origin of the question is Solid-State Switching Circuits topic in division Introduction to Solid-State Switching Circuits of Electric Drives

Answer 1

The correct option is (a) 46.16 A

Easiest explanation: The average value of diode current in 1-Φ Full wave semi-converter is Io(π+α÷2π). It is the average value of the diode current. Iavg = Io(π+α÷2π)=75.2(.61)=46.16 A.
