<p>A circuit for preventing reverse voltage breakdown in the thyristors of center-tapped source inverters. A plurality of clamp diodes are utilized to limit the reverse voltage across inverter thyristors in the presence of the voltage spikes produced by the inductances of the inverter during commutation. The reverse voltage is limited to a value low enough to protect the thyristors from reverse voltage breakdown and yet high enough to assure a relatively short reverse recovery time.</p> |
