ABSTRACT:
A transient suppression circuit suppresses transients on a dc power bus, extending between a power supply and a load which carries a first voltage having a nominal value, by charging a capacitor to a second voltage greater than the nominal voltage, detecting a threshold at which the first voltage drops below its nominal value by more than a first predetermined amount and coupling energy from the capacitor to the bus to compensate for the drop in voltage in response to detecting the threshold.
