Beschreibung
Zusammenfassung:	The embodiment of the invention discloses a power supply circuit and power supply equipment thereof. The power supply circuit comprises a transformer; the output filtering module is used for processing the induced voltage generated by the third winding into output voltage; the direct current feedback control module is used for controlling the output voltage of the output filtering module to a first target voltage; the alternating current feedback control module is used for adjusting the output voltage of the output filtering module to a second target voltage; the first target voltage is different from the second target voltage, so that the direct current feedback control unit or the direct current feedback control unit is in a feedback overvoltage state when the alternating current input power supply and the direct current input power supply are simultaneously input. The direct current feedback control module and the alternating current feedback control module are arranged on the transformer to achieve transf
