Beschreibung
Zusammenfassung:	The invention relates to the technical field of power supplies, in particular to a parallel low-voltage large-current output direct-current power supply device and a control method. The device comprises an AC input EMC module, an AC/DC power factor correction module, an AC working mode DC/DC low-voltage output module, an AC working mode DC/DC high-voltage output module, an intelligent charging module, a battery working mode DC/DC low-voltage output module, a battery working mode DC/DC high-voltage output module, a high-low voltage output switching controller and a signal sampling processing and control module. And a storage battery pack and a DC output EMC module. According to the low-cost reliable wide-voltage-range large-current output circuit provided by the invention, the output voltage and current data are acquired through software to control the high-voltage and low-voltage output switching circuit, so that the fault rate and the cost of a parallel power supply can be greatly reduced and the reliability
