Abstract
A method includes detecting a modulating undervoltage state having transients above an undervoltage threshold and triggering a protection upon detecting the modulating undervoltage state. The method can include detecting a steady state undervoltage condition, wherein triggering a protection includes triggering the protection upon detecting the steady state undervoltage condition or the modulating undervoltage state. A system includes a power source including a feedback sensor at a point of regulation (POR) of the power source configured to generate feedback indicative of voltage at the POR. A controller is operatively connected to receive the feedback. The controller includes controller logic that is configured perform a method as described above.
