Description

Combined type energy-saving UPS and bidirectional transducer module and power transferring method
Technical field
The present invention relates to a kind of UPS (Uninterruptible Power System, UPS), relate in particular to a kind of combined type energy-saving UPS that has alternating current output port and DC output end mouth concurrently, and relevant bidirectional transducer module and power transferring method.
Background technology
(Uninterruptible Power System UPS) is the protective device of visual plants such as computer equipment, monitoring instrument, fire-fighting equipment, Medical Instruments to UPS.When civil power took place to interrupt, UPS can promptly replace civil power, and the instrument and equipment even load of being protected to avoid causes shutdown or damage because of the power breakdown of moment.On the other hand, work as power-fail, for example, electric voltage exception (comprising overtension, low excessively), or when producing moment spiking etc. and be enough to power quality problem that the equipment that influences runs well because of thunderbolt, the alternating current of the exportable cleaning of UPS provides load to use.
At first, see also Fig. 1, this figure is the system architecture schematic diagram of UPS 10 in the prior art.As shown in Figure 1, UPS 10 has comprised input port 100, relay 102, charge circuit module 106, storage battery (Secondary battery) 108, (Boost) module 110 of boosting, converter (Inverter) module 112, monitoring module 120 and output port 104.Input port 100 is coupled to electricity network, to accept the input of electric main; Output port 104 output AC electricity are to external loading.
Fig. 1 UPS 10 belongs to off-line type UPS (Off-line UPS, or be called standby mode UPS (Passive standby UPS)) classification, it is characterized by to do power supply with relay 100 and switch.When electric main was normally imported, relay 100 was for starting (On/Close) state, and electric main can directly power to the load via output port 102.When electric main lost efficacy, relay 100 was for breaking (Off/Open) state, and powered to the load by the UPS 10 inner alternating currents that produce this moment.In Fig. 1, the power transmission path when transmission path A, B represent electric main normally with inefficacy respectively.
Input port 100 is connected in electricity network, to accept the input of electric main.Monitoring module 120 is coupled to input port 100, and the electric main of surveying input electrically is normal or unusual, and then the running of control UPS 10.Electrically normal when electric main, when relay 100 be starting state, charge circuit module 106 was converted to electric main direct current and carries out step-down, so that storage battery 108 is charged.When the electric main inefficacy, relay 100 is switched to when breaking state, and the electric power of storage battery 108 just begins to be output use, and the direct current of 110 pairs of storage batterys of boost module, 108 outputs boosts.Converter module 112 is then utilized inner bridge circuit, and the high voltage direct current that boost module 110 is exported is converted to the alternating current that meets mains frequency, powers to the load by output port 104.
Except above-mentioned off-line type UPS classification, UPS commonly used also comprises online UPS (On-line UPS) classification, and the binding of each module is different with the off-line type UPS in this type of UPS.Described online UPS is converted to direct current with electric main, and this direct current charges to storage battery on the one hand, is the alternating current output that meets mains frequency through the converter module converts on the other hand.When electric main lost efficacy, storage battery discharged direct current power, and this direct current boosts via boost module, was alternating current output by the converter module converts again.
Can find out that by above-mentioned explanation the boost module as the macro-energy voltage transitions in UPS was only just played a role when electric main loses efficacy.Especially in the off-line type UPS, when electric main was normally imported, boost module and converter module be not running all.Waste for material resources is apparent.On the other hand, digital devices such as portable computer, mobile phone, carry-on digital audio-video player use the direct current running mostly.In case have a power failure, the alternating current that said apparatus must be supplied UPS by electric pressure converter indirectly is converted to direct current, again device is done power supply or charging.The electric power of UPS is exported from storage battery, is alternating current via internal conversion, has caused power loss, through the external voltage transducer alternating current is converted to direct current again, will cause power loss once more.Make the electric power that is transferred to device from storage battery often have only 50% to 60% service efficiency, cause waste, do not meet environmental requirement at present for using energy source.
Now, portable computer and all kinds of digital device are extensive use of, and cause information to run off and the device damage for fear of power failure, and UPS has entered the application category of digital home.Yet, known UPS be operating as a kind of uneconomical and mode of wasting energy.In view of this, this case is proposed.Combined type energy-saving UPS proposed by the invention is except providing alternating current, and having concurrently provides galvanic function, to promote the usefulness of UPS, makes it satisfy popular needs, and meets at present for environmental protection and requirements of saving energy.
