Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for fault detection in a power control system. In one aspect, a method includes measuring a plurality of values of a feedback voltage from a power control system over a period of time; determining a rate of feedback voltage change based on the measured values of the feedback voltage and a duration of the period of time; determining, with a controller, that the determined rate of feedback voltage change is smaller than a threshold rate of change; and in response to determining that the determined rate of feedback voltage change is smaller than the threshold rate of change, transmitting a fault indication signal to the power control system.
