Vc1, Vc2 and Vc3 are the forward break-over voltages of a thyristor for gate currents Ig1, Ig2 and Ig3. Which relationship is correct?
Correct answer A. Vc1 > Vc2 > Vc3 when Ig1 < Ig2 < Ig3
Explanation
Increasing gate current injects more carriers into junction J2, so the thyristor breaks over at a lower forward voltage. Higher gate current therefore means a lower break-over voltage.
