Abstract
A power supply may include a power converter circuit may be configured to control a magnitude of an output voltage, and generate a signal indicative of the magnitude of the output voltage. The power supply may include an over-power protection circuit that is configured to receive a feedback signal indicative of a magnitude of an input current of the power converter circuit. The power supply may include a control circuit that is configured to determine a magnitude of a requested power based on the signal indicative of the magnitude of the output voltage, and disable the power supply (e.g., control the magnitude of the output voltage to be zero volts) when the magnitude of the requested power is greater than a second threshold and the magnitude of input power indicated by the first feedback signal is less than a third threshold.
