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.

Abstract: A system may include a plurality of master lighting modules and a fixture controller. The fixture control may include a power converter circuit that is configured to generate a bus voltage on a power bus. The plurality of master lighting modules may be serially-coupled on the power bus. The fixture controller may include a control circuit that is configured to receive an indication of a magnitude of an end bus voltage at an end master lighting module. The end master lighting module may be the master lighting module that is located furthest from the fixture controller along the power bus. The control circuit may be configured to generate a target bus voltage control signal based on the magnitude of the end bus voltage. The power converter circuit may be configured to control a magnitude of the bus voltage based on the target bus voltage control signal.
