1.5 System Description
Fig 1- 3: UPS system
1.5.1 Transient Voltage Surge Suppression (TVSS) and EMI/FRI Filters
These UPS components provide surge protection and filter both electromagnetic
interference (EMI) and radio frequency interference (RFI). They minimize any surge or
interference present in the utility line and keep the sensitive equipment protected.
1.5.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC
power to regulated DC power for use by the inverter while ensuring that the waveform of the
input current used by the UPS is near ideal. Extracting this sinewave input current achieves
two objects:
The utility power is used as efficiency as possible by the UPS.
The amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being
protected by the UPS.
1.5.3 Inverter
In normal operation, the inverter utilizes the DC output of the power factor correction circuit
and inverters it into precise, regulated sinewave AC power. Upon a utility power failure, the
inverter receives its required energy from the battery through the DC-to-DC converter. In
both modes of operation, the UPS inverter is on-line and continuously generating clean,
precise, regulated AC output power.

Product description
7
1.5.4 Battery Charger
The battery charger utilizes energy from the DC bus and precisely regulates it to
continuously charge the batteries. The batteries are being charged whenever the UPS is
connected to utility power.
1.5.5 DC to DC Converter
The DC to DC converter utilizes energy from the battery system and raises the DC voltage
to the optimum operating voltage for the inverter. The converter includes boost circuit which
is also used as PFC.
1.5.6 Battery
The 6KS/10KS Standard includes value regulated, sealed lead acid, maintenance free
batteries inside. To maintain battery design life, operate the UPS in an ambient temperature
of 15-25°C.
1.5.7 Static Bypass
The UPS provides an alternate path for utility power to the connected load in the unlikely
event of a UPS malfunction. Should the UPS have an overload, over temperature or any
other failure condition, the UPS automatically transfers the connected load to bypass.
Bypass operation is indicated by an audible alarm and illuminated amber Bypass LED. To
manually transfer the connected load from the inverter to bypass, press the “ + ”
button once.
NOTICE: The bypass power path does NOT protect the connected equipment from
disturbances in the utility supply.
1.6 UPS Working Mode
Normally UPS working mode include normal mode, bypass mode, battery mode, ECO mode,
frequency converter mode, self aging mode.
Normal Mode
Shown as Fig 1-4, rectifier supply DC supply to inverter, the load is feed by inverter. Charger
