Quizplus · Accepted Answer

Anode current interruption and forced commutation are the two methods commonly used to return a Silicon-Controlled Rectifier (SCR), also known as a thyristor or SUS, to its nonconducting state. Anode current interruption involves reducing the current flowing through the SCR to below its holding current, while forced commutation involves using external circuitry to reverse the current or voltage conditions, thereby turning off the SCR.
