Accompanying drawing explanation
Fig. 1 is overall system architecture figure.
Fig. 2 is rectified power factor correcting circuit figure.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further detailed.
As shown in Figure 1: this utility model includes EMI/RFI wave filter 1, rectified power factor correcting circuit (APFC) 2, inverter circuit 3, filter circuit 4, STS 5, stepping-up/stepping-down chopper circuit 6, set of cells 7, isolated drive circuit 8, control circuit 9 and testing circuit 10.
EMI/RFI wave filter 1, rectified power factor correcting circuit (APFC) 2, inverter circuit 3, filter circuit 4, STS 5 connect in order, the outfan of EMI/RFI wave filter 1 is connected with another input of STS 5, another road outfan of filter circuit 4 is connected to control circuit 9, it is then passed through isolated drive circuit 8, final access inverter circuit 3, forming the structure of closed loop, another road of rectified power factor correcting circuit (APFC) 2 then exports and is connected with set of cells 7 to stepping-up/stepping-down chopper circuit 6.
Rectified power factor correcting circuit (APFC) 2 uses the single-phase APFC Double-closed-loop control circuit of outer voltage, current inner loop.DC/DC power inverter is added, due to not filtering before converting at DC/DC, so the sinuous pulsation voltage Ud of double half-waves of commutator output is directly inputted in DC/DC changer between single phase bridge type rectifier circu and filter capacitor C.In the case of ensureing output loading voltage stabilization, applied current feedback technique realizes single-phase bridge rectifier input power factor and is approximately the target of 1, detect and control the output electric current Id of commutator in real time, it is made to follow the change of the waveform of Ud, so that ac-side current Ii follows AC voltage Ui, reach PFC and be approximately the purpose of 1.
Set of cells 7 uses valve controlling sealed lead battery.
Stepping-up/stepping-down chopper circuit 6 uses buck-boost type DC/DC transducer.
When mains-supplied is normal, the Radio frequency interference of civil power and the electromagnetic interference of conduction type are after EMI/RFI wave filter, by suitable decay and suppression, it is more stable unidirectional current that one tunnel first passes through PFC (APFC) circuit conversion, then unidirectional current is made to be converted to the alternating current of frequency stabilization, voltage stabilizing by inverter circuit, finally by STS (STS) powering load.Another road carries out floating charge through buck circuit to valve control battery group, so that when civil power breaks down, set of cells can provide the electric energy of abundance to maintain its work to ups system.
When mains-supplied breaks down (power failure, line voltage are too low or too high), stop valve control battery being charged.By valve control battery group, inverter circuit is powered, is that AC energy is supplied to electrical equipment by the direct current energy inversion preserved in valve control battery group, be used for keeping the sustainable supply of electrical equipment power supply.
When mains-supplied is normal, and inverter goes wrong or during output overloading, STS (STS) is switched to bypass outfan by UPS immediately, allows system be operated in alternating current bypass state, civil power provides electric energy directly to electrical equipment.If owing to inverter circuit fault causes permutator STS to switch, UPS will send alarm signal;If cause STS to switch due to overload, after overload situations disappears, STS STS can switch back into again inverter circuit outfan again.
It thus is seen that on line type UPS is whether when civil power is normal, or when civil power breaks down, it is all to be provided by the inverter circuit of ups system the power supply of electrical equipment.It will be appreciated that, on line type UPS system fundamentally reduces interference and the fluctuation voltage harm to electrical equipment of civil power, thus system reached veritably without time break, in high precision, disturb little, the purpose of voltage stabilizing.
