Description
Technical field
The utility model relates to and uses solar energy for main electric power system of replenishing as power devices and civil power, is specifically related to the solar energy alternating current-direct current and uses the illuminalive power-supply device with.
Background technology
At present; Generally all there is the problem of the electricity shortage that back-up source guarantees to cause under long-time overcast and rainy or other situation in solar electric power supply system; Wherein the arbitrary way of back-up source has two kinds: first kind is that solar DC is directly used electric with to alternating current-direct current, and back-up source converts direct current to through charger and is supplied to alternating current-direct current to use electric with; Second kind be solar powered convert to exchange through inverter be supplied to alternating current-direct current to use load with, back-up source is inserted by the inverter bypass.First kind of application can be used the electric energy that solar cell sent fully; But charger rectification meeting loss part electric energy when back-up source replenishes; And second kind can loss part electric energy when being applied in inversion, but bypass city can the loss point electric energy when switching.Therefore, these two kinds traditional back-up sources insert solar electric power supply system and exist great energy loss problem at present.
Summary of the invention
The utility model exists great energy loss problem in order to overcome traditional back-up source access solar electric power supply system; And provide a kind of solar energy alternating current-direct current to use the illuminalive power-supply device with; This device both can have been realized the direct direct current supply of traditional solar energy; Can need not charger again and directly switch to mains-supplied, make solar power generation and mains-supplied maximum using.
The technical scheme that the utility model adopts is:
The solar energy alternating current-direct current is used electric supply installation with; Comprise that solar panel array, solar powered control cubicle, alternating current-direct current use switch, batteries, alternating current-direct current with and use load with and form; It is characterized in that: solar powered control cubicle is used switch with solar panel array, batteries, alternating current-direct current respectively and is linked to each other, and alternating current-direct current is used load with and used switch with alternating current-direct current and link to each other.
Alternating current-direct current is used switch with; Comprise that isolation rectification circuit, buffer circuit and civil power insert switch and form; Civil power inserts switch through civil power and links to each other with the buffer circuit input; Direct current links to each other with the isolation rectification circuit input end, and isolation rectification circuit output end, buffer circuit output are all used load with alternating current-direct current and linked to each other, thereby realizes uninterrupted to the alternating current-direct current electric.
The solar panel array of the utility model, solar powered control cubicle, isolation rectification circuit, buffer circuit, batteries, alternating current-direct current are used load with and all can be obtained from the market purchase.
The utility model is used solar panel array, batteries, alternating current-direct current with switch and is connected to corresponding port on the solar powered control cubicle, and alternating current-direct current is used load with and used switch with alternating current-direct current and be connected.Solar powered control cubicle is that the control solar panel array discharges and recharges electricity to batteries, the control alternating current-direct current use with switch alternating current-direct current is used with load discharge and direct current and civil power is exchanged between switching.Concrete control circuit is seen Fig. 1.Its control procedure is: solar panel array is to battery charging; When need of load is supplied power, using the batteries electric energy with switch through alternating current-direct current offers alternating current-direct current and uses load with; When accumulator electric-quantity is not enough, civil power is linked into alternating current-direct current uses system with and replace storage battery to continue to use electric with to alternating current-direct current thereby start city's electrical switch.
The beneficial effect of the utility model is: used alternating current-direct current to use device with, reduced the electric energy that loses in solar electric power supply system inversion or the ac-dc conversion greatly.Multiple more electric more than 15% than similar solar electric power supply system economize on electricity.
