According to the AC-DC power supply system, the DC/DC power supply devices connected with the DC power supply and the AC/DC power supply devices connected with the AC power supply are electrically connected in parallel to the power control circuit board, so that a standby power supply device can continuously output direct power to the electronic device when the power supply of the system is abnormal.
Description
Technical field
The present invention relates to electric power system power source field, more specifically, relate to a kind of alterating and direct current source supplying system.
Background technology
The quality one of power supply unit is to being the principal element that computer system maintains stable running and quality, being showing improvement or progress day by day especially in the face of science and technology, electronic installation (such as hard disk, central processing unit, the electronic installations such as CD writer) also more and more higher to the relative requirement of power quality, but because of the instability of input power quality, the overall output power quality of power supply unit is failed gradually, if especially input power supply produces power breakdown problem, then computer system will quit work immediately and cause electronic installation to operate interruption, the loss of significant data or data will be caused like this.
For solving power breakdown problem, there is reserve source of electrical power supply device, it mainly adopts parallel electric power to connect the power supply unit of more than two, when wherein a power supply unit produces abnormal failure, all the other power supply units still will continue the sub-device running of stable output power supply, then have the DC-DC power supply unit (Dcmc PowER) and the ac/dc power supply unit (AC/DC POWER) two kinds being connected AC power that connect DC power supply according to the electric power conversion regime of power supply unit.
If existing reserve source of electrical power supply device on the market connects multiple ac/dc power supply unit compositions of AC power, when although wherein a power supply unit produces and abends action, all the other power supply units can maintain electric power and export, if but the AC interruptions of input electric power, even if then all power supply units are normal, because of non-transformer input, then all power supply units will stop action and stop electric power, although for avoiding the situation of AC interruptions, UPS is equipped with mostly, input electric power is provided to start when outside AC interruptions, but for electronic installation, its reaction rate maintaining continuing power running is quite of short duration, before UPS restarts input electric power, electronic installation first decommissions and causes data to lose, that is, computer system again must be started shooting and just can be restarted electronic installation, still the puzzlement of user is caused.
If reserve source of electrical power supply device is the multiple DC-DC power supply unit compositions connecting DC power supply, because DC power supply is multiple dc-battery composition, relatively AC power, user can help the service time of calculating DC power supply voluntarily, and the DC power supply of full charging amount is changed in timing, but, because rechargeable battery will loss and reduce its actual availability electricity gradually after repeatedly discharge and recharge, like this user will be caused to judge the real spendable electricity of DC power supply and time by accident, and replacing in real time causes computer system to interrupt, in addition, the available power of rechargeable battery is limited, to a large amount of and continue to provide computer system to use, for user, not only power cost is quite high, the required cost of getting the raw materials ready for depositing rechargeable battery is also considerable.
Summary of the invention
The invention provides a kind of low cost, power of alterating and direct current Absorbable organic halogens changes the alterating and direct current source supplying system used.
In order to reach above-mentioned technique effect, technical scheme of the present invention is as follows:
A kind of alterating and direct current source supplying system, comprising: at least one connection DC power supply A also carries out power office's reason with the DC-DC power supply unit exporting direct current power; At least one connection AC power B rectified power process are to export the ac/dc power supply unit C of direct current power; At least one control circuit power plate D, provide the parallel electric power of described DC-DC power supply unit E and described ac/dc power supply unit C to connect, described control circuit power plate D exports electronic installation F to after integrating described direct current power.
Further, described many group DC-DC power supply unit E are connected to a DC power supply A jointly.
Further, described many group ac/dc power supply unit C are connected to an AC power B jointly.
Further, described DC-DC power supply unit E and described ac/dc power supply unit C is connected with a power-balance unit G.
Further, described control circuit power plate D has the electric power output circuit I of an integration direct current power.
Further, described control circuit power plate D also has one in order to detect the circuit for detecting J of DC-DC power supply unit 40E and ac/dc power supply unit C operating state.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
The reserve source of electrical power supply device possessing AC and DC power input according to the present invention can continue the advantage of low cost of utilization and the advantage of DC power supply Absorbable organic halogens replacing use in a large number in conjunction with AC power, adopt the reserve source of electrical power supply device design of duplicate supply input, allow power supply unit when arbitrary electric power input source interrupts, all sustainable output direct current power to electronic installation, to make its normal operation.
