Description

Technical Field

[0001] The invention relates to the technical field of dual power supplies, in particular to a power supply device with dual power supply modules. Background Art

[0002] A dual power module is a power supply system composed of two power modules. The power supply device with dual power modules in the prior art can smoothly transfer the system load to the backup power supply when the main power supply fails or the main power supply voltage is reduced, so as to achieve uninterrupted power supply and ensure the continuity and stability of the power supply system. However, when the main power supply voltage is reduced, it switches to the backup power supply, and the power supply cannot reasonably utilize the power provided by the main power supply and the power provided by the backup power supply. When the backup power supply is composed of a battery pack, the power consumption of the backup battery will increase and the endurance of the backup power supply will be reduced. In addition, when the backup power supply is charged and discharged, it is necessary to adopt a related charge and discharge control device to control the charge and discharge, which increases the cost of the power supply device, and therefore needs to be improved.
