ABSTRACT:
An active clamp circuit for controlling over-voltage, surge conditions in electrical circuits. The active clamp includes a varistor which is switched into a circuit by a high power switch upon the detection of a surge condition. The use of a MOS Controlled Thyristor ("MCT") as a means for the switching the varistor permits the circuit to withstand a high di/dt and surge current while maintaining both on and off gated control of the switch.
