Abstract
The invention discloses a dual-port input switch power supply which is applicable to information equipment such as a computer. On the basis of the conventional alternating current single-input-port switch power supply, a direct current input channel is added. By adoption of a dual-port structure, uninterruptible power supply can be economically realized, common utility power which is input from an alternating current port is used for primary application, an over-voltage protection circuit in an alternating current channel and direct current which is input from a direct current port filter the over-voltage and low voltage of the utility power; and when alternating current utility power is interrupted, standby input direct current ensures the uninterruptible power supply of the information equipment. Along with economic development, the power supply reliability of the common utility power is improved, the direct current for the uninterruptible power supply works with a load in short time, and requirements on the capacity and reliability of an external direct current power supply are reduced, so the construction cost of an uninterruptible power supply system is reduced.
Description
Technical field the present invention is applicable to the information equipment internal electric source.
Background technology is that the present information device interior of representative has adopted single port input switch power supply with the computer.Modern society gets into the information age, and the human lives highly relies on various information equipments, and the power supply reliability of information equipments such as computer has been proposed requirements at the higher level, and single port input switch power supply can not satisfy the power supply reliability requirement.
Summary of the invention task of the present invention provides a kind of dual-port input switch power supply of high power supply reliability.
Said dual-port input switch power supply is on the interchange single port input switch power supply basis of present standard, increases a direct current input channel.
Said interchange single port input switch power supply; Receive external electric energy from the ac input end mouth; After electromagnetic compatibility (EMC), rectification, power factor correction processing links such as (PFC); With the direct current form with electrical power storage in storage capacitor, form inner various low-voltage direct operating voltage through the DC-DC conversion more at last.Said direct current input channel receives outside direct current energy from DC port, after processing links such as electromagnetic compatibility (EMC), isolation, is transported in the storage capacitor.
Dual-port input switch power supply provides dual input mechanism, has improved power supply reliability, has accomplished the invention task.
Hereinafter combines accompanying drawing and embodiment that the present invention is further described.
Fig. 1 is dual-port input switch power principle figure.
Fig. 2 is the UPS For computer schematic diagram that adopts the dual-port Switching Power Supply.
Embodiment Fig. 1 has provided dual-port Switching Power Supply fundamental diagram.
Dual-port input switch power supply, AC imports one road electric energy from the ac input end mouth, through behind the electromagnetic compatibility (EMC), rectification, power factor correction processing links such as (PFC), with the direct current form with electrical power storage in storage capacitor; Receive the outside direct current energy in another road from direct-flow input end mouth DC; After processing links such as electromagnetic compatibility (EMC), diode-isolated; Be transported in the storage capacitor, the DC--DC converter utilizes the voltage at storage capacitor two ends to form inner various low-voltage direct operating voltage.
Fig. 2 is the UPS For computer schematic diagram that adopts the dual-port Switching Power Supply
After computer adopts the dual-port Switching Power Supply, can use economic mode to realize uninterrupted power supply.Common electric main at first through after the overvoltage protection from ac input end mouth AC input computer, after inside is passed through electromagnetic compatibility (EMC), rectification, power factor correction processing links such as (PFC) again, with the direct current form with electrical power storage in storage capacitor; Receive the DC uninterrupted electric energy in another road from direct-flow input end mouth DC, after processing links such as electromagnetic compatibility (EMC), diode-isolated, be transported in the storage capacitor, form inner various low-voltage direct operating voltage through the DC-DC conversion more at last.
Adopt to exchange main with, direct current reserve uninterrupted power supply principle, when electric main just often, at the voltage that the storage capacitor two ends form, make that the isolating diode in the direct current input channel is anti-inclined to one side by electric main, the direct current input current is zero; When the ac commercial power voltage is crossed low or during power failure, isolating diode positively biased to storage capacitor, guarantees that the DC--DC converter of back uninterruptedly forms inner low-voltage direct operating voltage from the direct current reserve electric energy automatic transport of DC port input; When electric main generation overvoltage, by the excess voltage protection filtering.
Because expanding economy; Common civil power power supply reliability improves; Guarantee that the direct current bringing onto load operating time of uninterrupted power supply is very short after adopting dual-port structure, external dc power capacity and reliability requirement descend, thereby have reduced structure uninterruptible power system cost.
