UPS DESCRIPTION

The UPS isastatic electric machinethatthroughthe conversion of energydrawn from the batteriesconnected to it,

The ups supply the load when the input line is present or not.
The ups is composed of:

  • Input PFC
  • Inverter
  • Statc ByPass
  • Battery
  • Control Logic

The picture show the schematic block of ups.

Input PFC

ThePFCinputis anAC / DC converterthat converts theinputAC voltageto DC voltagewhichis used tosupply the inverterandto charge the batteries.
ThePFC(Power FactorCorrector) allows you to presentto the mainsloadupswhatever it is,asa resistive load,absorbing energywithacosPHIclose to 1, normally0.99, reduces the harmonics injectedinto the power line by capacitive and inductive load and by non linear load.
The IGBT and the high performance DSP used in the PFC, permit to obtain the very high efficiency.
The start up of thePFCon theinput lineis controlled bya rampofchargein such a wayas to keepthe very low inrush current.

Inverter

The inverter willconvertthe DC voltageof thePFCandthe batteryinto AC voltagewhich is thensuppliedto the loadsconnected to the UPS.

The waveformof the output voltageis a sine wavewithavery low distortion, less than 3%, perfectlystabilizedin frequency andvoltage.
The inverterhas nooutput transformer, transformerless, and uses athree-phaseIGBTbridgewhichensuresreduced dimensionsandvery high efficiency.

Static switch

Theswitchingof the two linesoccurswhen they are inperfect synchronismalways ensuringa correct supplyto the load

Battery

The UPS batteriesfeed theloadsconnected to the UPSin case of lackof the electricity network, by ensuring amore or less longtimebackto the systemaccording to theircapacity.
The batteries aremaintenance freedry type.
During the charging , the PFC control the temperature and changing the charging curveas the temperature changes, ensuring aperfect chargeto the batteriesand a longlife

Control logic

The operation ofthe UPSis fully digital, including the generationof all signalsrequired to operatethe inverter andPfc.

To do thiseachPFCandinvertercontrol board, equipped with two performantDSP(Digital SignalProcessor), which control all the variablesina very short timealarms andevents that occurduring the operationof the UPS.
