POWER SUPPLY APPARATUS, METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/065075
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a power supply apparatus, method and system. The power supply apparatus comprises a first energy storage unit, a rectifier, an inverter and a switching unit, wherein one end of the rectifier is connected to a first input power source; the other end of the rectifier is connected to one end of the inverter, an output end of the first energy storage unit and a first input end of a load; the other end of the inverter is connected to an output end of the switching unit and a second input end of the load; a first input end and a second input end of the switching unit are respectively connected to the first input power source and a second input power source; the first input power source, the second input power source and the first energy storage unit jointly supply power to the load; and if a voltage outputted by the first input power source is less than a preset first threshold value, and a voltage outputted by the second input power source is less than a preset second threshold value, the first energy storage unit is used for supplying power to the first input end of the load, and power is supplied to the second input end of the load by means of the inverter. The power supply apparatus has relatively high reliability in terms of supplying power to a load.
