Summary: | The invention discloses a method for improving the safety and energy-efficient performance of a civilian electrical appliance, and an energy-efficient civilian DC power supply system. The power supply system comprises a DC power supply device, a constant voltage/current circuit, a DC load, an automatic load detection circuit and a control module, wherein the output end of the DC power supply system is connected with the input end of the constant voltage/current circuit; the output end of the constant voltage/current circuit is connected with the DC load; the automatic load detection circuit carries out real-time sampling on the voltage and/or current of the DC load and inputs sampling signals to the control module; the control module judges the load change of the DC load according to the input sampling signals and outputs PWM pulse signals to the constant voltage/current circuit according to the judgment results; and the constant voltage/current circuit adjusts the output power into an output power meeting th |
