<p>The protection circuit is used for semiconductors such as thyristors normally handling high power levels. Protection against supply voltage transients is supplied by an inductance (L) connected into the load to semiconductor current path with a capacitor (C) from the inductance load junction (A) to the control electrode (S) of the semiconductor. Where two thyristors are employed connected in parallel-opposition each thyristor has a capacitor between its gate and anode. A series resistor (R) may be included in the capacitor path, the inductance being common to both thyristors.</p> |
