Question

The area under the curve of the gate characteristics of thyristor gives the

(a) total average gate current

(b) total average gate voltage

(c) total average gate impedance

(d) total average gate power dissipation

This question was posed to me in an interview.

My question is based upon Thyristors-3 topic in section Power Electronics Devices of Power Electronics

Answer 1

The correct choice is (d) total average gate power dissipation

To elaborate: As the gate characteristics is a plot of Ig vs Vg  consisting of two curves one for the maximum values & other for the minimum the area between them gives the total average gate power dissipation. (A very important parameter in designing of the triggering circuits).
