Zusammenfassung:	The utility model provides an AC output paralleled power supply device which comprises at least two power supply modules which are connected in parallel to each other, and further comprises a guiding module, wherein, the power supply modules comprise an AC/DC conversion unit and a DC/DC conversion unit; the input terminal of the DC/DC conversion unit is connected with the output terminal of the AC/DC conversion unit; the AC/DC conversion unit converts an input AC voltage into a DC voltage, and then outputs the DC voltage to the DC/DC conversion unit; the DC/DC conversion unit converts an input DC voltage into a reference waveform DC voltage according to a reference signal, and then outputs the DC voltage to the guiding module; and the guiding module converts the paralleled output DC voltage of the power supply modules into an AC voltage, and then outputs the AC voltage to a load. The utility model which realizes AC output and connects the power supply modules in parallel by direct current has the advantages t
