The utility model content
The purpose of the utility model is to provide a kind of solar energy and city's electricity complementary power-supply controller, has solved solar power generation and can not satisfy load running and take, and the power supply approach is switched, with the problem of the normal operation of proof load.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of solar energy and city's electricity complementary power-supply controller; Comprise dc supply input mouth that is used to connect solar cell and the output port that is used for powering load, be sequentially set with on the circuit between said dc supply input mouth and the output port of power source DC-DC boost module, AC handover module;
Said AC handover module comprise direct-flow input end mouth and the ac input end mouth that is used to be connected civil power, the direct-flow input end mouth of DC-DC boost module is connected to the dc supply input mouth, connect afterwards AC the direct-flow input end of handover module;
Said controller also comprises central processing unit and voltage detection module, and said central processing unit is used to control the unlatching of DC-DC boost module or cut out; Said voltage detection module detects the voltage on the dc supply input mouth circuit, and outputs to central processing unit to detected value;
Said AC gate-controlled switch is arranged in the handover module; Voltage detecting value on the dc supply input circuit that said central processing unit comes according to the voltage detection module transmission that receives is controlled the conducting of gate-controlled switch or is closed, so realize AC the conducting switching between output and two inputs in the handover module.
Preferably, said controller also comprises an infrared communication module, and said central processing unit connects host computer through infrared communication module, and the information with the power supply state of present load exports host computer to simultaneously.
The beneficial effect of the utility model is: through in good time switching between control solar storage battery and the civil power; The situation that has prevented the electric interruption that sunlight causes when not enough takes place; The continuity and the reliability of load running have effectively been guaranteed; Can be applied to lighting, watch-dog even load, make things convenient for productive life, improve fail safe and production efficiency.
