Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the following technical solutions and technical features can be combined with each other.

[0034] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0035] The present invention mainly provides a power supply system, such as figure 1 As shown, the mains power is used to supply power to the AC load. Since the mains is AC power, a rectification module (rectification circuit) is needed to convert the AC power of the mains into DC power and output it to the AC load to provide power to the AC load. This embodiment also includes an inverter, which converts the DC power output by the rectification module into AC power and then outputs it to the AC load, so that the mains power can supply power for both the DC load and the AC load.

[0036] This embodiment also includes a first DC / DC converter, which can supply power to the storage battery, and the ci...

Abstract

The invention relates to the field of a power system and particularly to a power supply system. The power supply supplies power to a load by adopting mains supply alternating current electric energy; the power supply system comprises a rectifier module used for converting the mains supply alternating current electric energy into direct current electric energy to output, a first DC-DC converter connected with the rectifier module and used for converting the constant direct current electric energy into variable direct current electric energy, a storage battery connected with the first DC-DC converter and used for storing the variable direct current electric energy converted by the first DC-DC converter, a second DC / DC converter connected with the rectifier module and used for converting the constant direct current electric energy into variable direct current electric energy, and a supercapacitor connected with the second DC-DC converter and used for storing the variable direct current electric energy converted by the second DC-DC converter.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power supply system. Background technique [0002] The power supply system is a system composed of a power supply system and a power transmission and distribution system that generates electrical energy and supplies and transmits it to electrical equipment. In the current prior art, the load is usually powered by converting the mains alternating current into direct current. However, once the mains power grid collapses, the load cannot receive electric energy, and the continuous power supply of the load cannot be guaranteed. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a battery comprising a supercapacitor and a storage battery, capable of continuously supplying power to DC loads when the mains power collapses. [0004] The present invention adopts following technical scheme: [0005] A power supply system, w...
