"Illustrate the commutation process in a thyristor. Show a thyristor in a circuit with current flowing when ON. Include two cases: 1) Natural commutation in an AC circuit where current naturally drops to zero every half cycle, and 2) Forced commutation in a DC circuit with an LC or auxiliary circuit forcing current to zero. Use arrows to show current flow, a gate pulse triggering the thyristor, and indicate the moment the current drops to zero turning the thyristor OFF. Diagram style, clear labels for ON, OFF, AC, DC, and commutation." Mehr sehen
