System Description

3. SYSTEM DESCRIPTION

3.1 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.

3.2 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.

3.3 Inverter

In normal operation, the inverter utilize 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.
