The rating of GTO is 100V, 25A. It controls the power from a 600V supply and the load is 30 ohm. The voltage drop is 2.2V and the average gate power is 10W, Ia for turn on is 0.5A and for turn-off is -25A. Determine:
a. Device power gain.
b. Device turn on current gain.
c. Device turn off current gain.
