Can and energy-storage battery, build set of domestic power supply auto-parallel device, realize smart home and uninterrupted power source without seaming and cutting
Change, user's uninterrupted power supply is ensured when major network has a power failure, auto-parallel can be realized when needing online to generate electricity, realize highly reliable
The auto-parallel device of property.
The content of the invention
The purpose of this utility model is, open according to the problems that exchange back-up source and DC back-up power supply are present
A kind of domestic power supply auto-parallel device.
The technical solution of the utility model is that a kind of domestic power supply auto-parallel device, including dsp controller, exchange connect
Mouth mold block, DC interface module and main network interface module.Exchange interface module, DC interface module and main network interface module difference
Connection dc bus；Exchange interface module, DC interface module and main network interface module connect DSP by data telecommunication line respectively
The corresponding interface of controller.
3 modules are separate, and completing energy by dc bus transmits, and is entered with dsp controller by data telecommunication line
Row communication, control is coordinated by DPS controllers to each module.
Exchange interface module and main network interface module are constituted by AC/DC circuits, measuring circuit, the part of protection circuit three.
The input connection dc bus of AC/DC circuits；The output end of AC/DC circuits connects measuring circuit and protection circuit respectively；Survey
The output end for measuring circuit connects dsp controller by data telecommunication line.
DC interface module is made up of DC/DC circuits, measuring circuit, the part of protection circuit three.The input of DC/DC circuits
Connection dc bus；The output end of DC/DC circuits connects measuring circuit and protection circuit respectively；The output end of measuring circuit passes through
Data telecommunication line connects dsp controller.
The beneficial effects of the utility model are, the utility model device can combine exchange back-up source, direct current solar energy and
Energy-storage battery, builds set of domestic power supply auto-parallel device, realizes the seamless switching of smart home and uninterrupted power source, when
Major network ensures user's uninterrupted power supply when having a power failure, and auto-parallel can be realized when needing online to generate electricity, and realizes high reliability
Auto-parallel device.
The utility model device is applied to the power supply of smart home and uninterrupted power source.
