Claim Text:
1. A power supply system, comprising: an alternating current (AC) power input; a direct current (DC) power output configured to output DC power to a load of the power supply system; a power conversion unit configured to convert AC power from the AC power input to DC power for the DC power output, the power conversion unit comprising a power conversion circuit and a first controller, the first controller configured to adjust an operating mode of the power conversion circuit according to a circuit parameter, the first controller further configured to set the circuit parameter to a factory default; the power conversion unit further comprises a phase modulation circuit connected to the first controller and the DC power output, the phase modulation circuit configured to determine a variable power of the DC power output and further configured to send a recovery signal to the first controller in response to the variable power exceeding the threshold value, and the first controller configured to set the circuit parameter to a recovery value in response to the recovery signal; a DC meter configured to measure the DC power of the DC power output and further configured to send a power signal indicative of the measured power; and a second controller configured to receive the power signal from the DC meter and further configured to output a parameter setting signal to the first controller based on the measured power indicated by the power signal, and the second controller further configured to make a determination that the measured power is less than a threshold value and further configured to send the parameter setting signal to the first controller in response to the determination that the measured power is less than the threshold value, wherein the first controller is configured to determine a value of the circuit parameter based on the parameter setting signal.
