Abstract
An overvoltage detection system includes a sensed voltage; an active reference module that generates an active reference signal having a magnitude that varies inversely with a magnitude of the sensed voltage; and a timed trip module that includes a resistor and capacitor, and detects an overvoltage condition as a function of the sensed voltage, the active reference signal, and time.
