摘要：The invention relates to supplying power. So to provide a DC voltage based onan AC voltage with a low level of electro-magnetic interference while allowing for a

desired power factor, the power supply circuit comprises an input stage unit, an energystorage element, and an output stage unit, wherein the power supply circuit is arrangedfor a first mode and a second mode, wherein, in the first mode, the input stage unitstores energy in the energy storage element based on received AC voltage and theoutput stage unit does not receive energy from the energy storage element forproviding the DC voltage, wherein, in the second mode, the input stage unit does notstore energy in the energy storage element and isolates the energy storage elementfrom the AC voltage input and the output stage unit receives energy from the energystorage element for providing the DC voltage.
