摘要：A power supply apparatus includes a converter to convert AC power into DCpower, an SMPS to convert the DC power into DC powers desired by loads, a capacitor to

interconnect the converter and the SMPS, a PTC element connected to the converter, afirst switch connected in parallel with the PTC element, and a second switch connected inseries with the first switch. The method includes turning on the second switch to startcharging of the capacitor, turning on the first switch to charge the capacitor to a targetvoltage level, and turning off both the first switch and second switch if a voltage acrossthe capacitor rises over the target voltage level, to discharge the voltage across thecapacitor so as to lower the voltage across the capacitor to the target voltage level orlower.
