UPS（Uninterruptible Power Supply）That is uninterrupted power source., can be steady with voltage stabilizing when civil power is normal
Frequently；When civil power powers off, the power protective equipment of power supply a period of time can be maintained by the energy storage device of itself.Traditional
UPS electric power systems are mainly made up of main components such as rectifier, battery, inverter and change-over switches.
On the one hand rectifier converts alternating current to direct current electricity output, the direct current of another aspect rectification output is battery
Charging voltage is provided.After civil power powers off, battery still can continue the energy source of power supply as UPS electric power systems, its
UPS electric power systems can continue to the time of power supply after amount of capacity decision civil power power-off.When civil power is normal, rectification output
Direct current is electric power storage, and pond provides charging voltage, energy is stored in battery；When civil power powers off, battery will be in civil power
The energy preserved under normal circumstances, externally it is released to other components and energy is provided.DC conversion is that height is steady by inverter
The device of fixed alternating current.The whole UPS of change-over switch selectivity carries out patten transformation.
As shown in figure 1, on line type UPS of the prior art, civil power be divided into after being accessed by wave filter mains-supplied circuit and
UPS power supply circuits, change-over switch selection switching mains-supplied circuit and UPS power supply circuits externally export, wherein UPS power supply circuits
Include rectifier, inverter, charger and battery, no matter whether civil power is preferable, and UPS is constantly in the state of work.
When UPS power supply circuits break down, it is load supplying that change-over switch, which switches to mains-supplied circuit, and its essence is will only pass through
The civil power for crossing filtering is directly load supplying.When civil power is normal, on the one hand treated civil power is load supplying, on the other hand
Charged by charger for battery.For civil power quality disturbance very greatly or in the case of electricity of cutting off market, battery is load supplying.Online
On the one hand formula UPS can provide the supply voltage of high quality for load, on the other hand when civil power power-off or very poor grid condition not
Switching time be present, thus be adapted to continual electric power system for a long time, be suitable for the exigent place of electricity quality.
But on line type UPS of the prior art charges due to being directly over civil power in charging process for battery, because
And battery will necessarily produce interference to mains-supplied circuit, and battery does not possess safeguard measure yet in charging process,
Easily cause battery damage when civil power fluctuates.And on line type UPS of the prior art is in use to the shape that works
The monitoring of condition is substantially insufficient.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of on line type UPS.
The utility model is adopted the technical scheme that to solve technical problem present in known technology:
On line type UPS of the present utility model, including wave filter, rectifier, inverter, charger, battery and conversion are opened
Close, civil power is divided into mains-supplied circuit and UPS power supply circuits, change-over switch selection switching mains-supplied electricity after being accessed by wave filter
Road and UPS power supply circuits externally export, and wherein UPS power supply circuits include rectifier, inverter, charger and battery, UPS
Also include pfc circuit in power supply circuit and BUS electric capacity, rectifier are connected with pfc circuit, pfc circuit connection BUS electric capacity, BUS
Electric capacity connects inverter and charger respectively, and charger charges for battery, and the output of battery is connected with pfc circuit.
The utility model can also use following technical measures：
Described wave filter includes input filter and output filter, and civil power is inputted by input filter, change-over switch
It is connected with output filter, circuit output is drawn by output filter.
More described on line type UPSs are in parallel, and are connected by output bus with load, are connected by communication bus logical
Module is interrogated, communication module is connected with monitoring host computer again.
The utility model has the advantages and positive effects of:
In on line type UPS of the present utility model, pfc circuit is connected to after the rectified device of civil power of access, passes through pfc circuit
Charge for BUS electric capacity, then charged by BUS electric capacity for battery, charging is not directly to be carried out by civil power, and battery is not to civil power
Power supply circuit has an impact, and also avoids the probability that commercial power charged overtension produces infringement to battery as far as possible.Additionally by
Multiple on line type UPSs in parallel are simultaneously load supplying, improve the stability of power supply, while by monitoring host computer to each online
UPS is monitored, and also improves the controllable and reliability powered in use.

Embodiment
The technical solution of the utility model is described in detail below by way of the drawings and specific embodiments.
As shown in Figures 2 and 3, on line type UPS of the present utility model, including wave filter, rectifier, inverter, charger,
Battery and change-over switch, civil power are divided into mains-supplied circuit and UPS power supply circuits, change-over switch selection after being accessed by wave filter
Switching mains-supplied circuit and UPS power supply circuits externally export, and wherein UPS power supply circuits include rectifier, inverter, charging
Device and battery, also include pfc circuit in UPS power supply circuits and BUS electric capacity, rectifier are connected with pfc circuit, pfc circuit
Connect BUS electric capacity, BUS electric capacity connects inverter and charger respectively, and charger is that battery charges, the output of battery and
Pfc circuit is connected.
Do not charged a battery in UPS power supply circuits by civil power directly, but the civil power after rectification is passed through
Pfc circuit charges to BUS electric capacity, and on the one hand BUS electric capacity is load supplying by inverter, be on the other hand by charger
Battery charges.When civil power powers off, by battery through inverter powering load, work is continuously stablized with proof load
Make；When UPS power supply circuits break down, after filtering after civil power through the direct powering load of mains-supplied circuit, to protect
Card load continuously works.
