Abstract
The solar powered power pack of a kind of desktop computer.Its structure is comprised of solar electric power supply system and power pack two parts.Three high-power adjustable step-down high-efficiency power modules of DC-DV15A synchronous rectification for power pack, adjust to 12V, 5V, 3.3V,-12V-5V exports with 7912 and 7905 three terminal regulators, with D.C. contactor, make the master switch of power supply, with panel-mounted P cock, control, above-mentioned device is contained in box, replaces original 220V Switching Power Supply box in desktop computer.Two groups of 12V and 5V are connect on four-core plug, for CD-ROM drive hard disk etc., with 24 core winding displacements, connect mainboard socket.Solar electric power supply system is that 27V-29V solar cell charges a battery by operating voltage.Thisly with solar cell, charge a battery and make power supply, energy-conservation with the step-down of the high-power adjustable voltage dropping power supply module of synchronous rectification, with D.C. contactor, control the break-make of power supply and can not draw orphan.Be applicable to family, disaster area, areas without electricity use.
Description
Technical field
The utility model relates to a kind of computer power, especially solar powered computer power.
Background technology
At present, known desktop computer 220V AC-powered, when areas without electricity or power failure, be reverse into 220V alternating current with accumulator uses to computer, because inverter efficiency does not only have percent 85 to percent 90 not etc., add the loss of Switching Power Supply, waste very much not energy-conservation.
Summary of the invention
Not energy-conservation with inverter in order to overcome desktop computer, the utility model provides with solar powered power supply, replaces original Switching Power Supply.
The utility model solves the technical scheme that its technical matters adopts: it is comprised of solar electric power supply system and power pack two parts.Power pack is 98 percent by three conversion efficiencies, the high-power adjustable step-down high-efficiency power module of model DC-DV15A synchronous rectification, 24V is adjusted to output 12V, 5V, 3.3V by three modules, for the negative 12V below solution 1A and the power supply of negative 5V, with 7912 and 7905 three terminal regulators outputs.For solving the direct current of large electric current, when disconnecting, closing, to draw orphan, cause switch contact adhesion and blow, the D.C. contactor that employing coil DC voltage is 24V is made the master switch of power supply, with panel-mounted P cock, control, above-mentioned device is contained in box, replaces original 220V Switching Power Supply box in desktop computer.Positive 12V and positive two groups of power supplys of 5V are picked out on four-core plug, for CD-ROM drive, hard disk etc., with 24 core winding displacements, with original connection, equally sit in the right seat (switching line, reset line do not connect) on 24 core plugs, connect mainboard socket.Solar electric power supply system is to be that 27V-29V solar cell needn't worry to overcharge damage accumulator to 24V accumulator floating charging and cycle charging (the highest cycle charging voltage of accumulator of 12V is 14.6V) by operating voltage.
The beneficial effects of the utility model are, utilize solar cell to make desktop computer power supply to the charge in batteries of 24V, energy-conservation with the step-down of the high-power adjustable voltage dropping power supply module of synchronous rectification, control the break-make of power supply with D.C. contactor, can arcing.
accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 the present embodiment structure cut-open view.
Fig. 2 power pack circuit theory diagrams.
In figure 1, shell 2 ,+12V module 3 ,+5V module 4 ,+3.3V module 5 ,-5V voltage stabilizer 6 ,-12V voltage stabilizer 7, D.C. contactor 8, four-core plug 9,24 core thread plugs 10, power supply take a seat 11, power input plug 12, connect wire 13, plug 14, solar cell 15,24V accumulator 16, accumulator accessory power outlet 17, accumulator input socket 18, battery plug 19, power switch.
Embodiment
In Fig. 1, solar cell (14) connects battery plug (18) by connection wire (12) and is inserted on accumulator input socket (17), give the charging of 24V accumulator (15), with connecting wire (12) Electric plug with shutter (13), connect accumulator accessory power outlet (16) and power input plug (11).In shell (1), power input socket (10) is electrically connected to D.C. contactor (7) through switch (19), connect+12V of its output module (2)+5V module (3)+3.3V module (4)-5V voltage stabilizer (5)-12V voltage stabilizer (6), + 12V and+5V connects four-core plug (8) ,+12V+5V+3.3V-12V-5V connects 24 core thread plugs (9).In Fig. 2,24V is anodal gets back to negative pole by D.C. contactor (7) and switch (19), when D.C. contactor (7) is switched on, its contact A and B connect, and 24V direct current is connected the power supply of module and voltage stabilizer, from+12V module (2), export positive 12V, from+5V module (3) output 5V, from+3.3 modules (4), export positive 3.3V, from-the negative 5V of 5V voltage stabilizer (5) output, from-the negative 12V of 12V voltage stabilizer (6) output.
