There are nine common types of power problems, including power failure, power sag, power surge, undervoltage, overvoltage, switching transient, line noise, frequency variation and harmonic distortion. Based on three UPS topologies, Eaton offers a wide range of UPS solutions to provide an appropriate level of power protection against different power problems and failures.
Passive standby topology (off-line) is the most frequently
used UPS topology for protecting PCs against power failure,
power sag and power surge. In normal mode, the UPS supplies
power to the application directly from the mains, filtered but
without active conversion. The battery is charged from the
mains. In the event of a power cut or fluctuation, the UPS
delivers stable power from the battery. The advantages of this
topology are low cost and adequacy for office environments.
Passive standby topology is not suitable if the power supply is
of low quality (industrial sites) or subject to frequent disruptions.
Line interactive topology is used for protecting enterprise
networks and IT applications against power failure, power sag,
power surge, undervoltage and overvoltage. In normal mode,
the device is controlled by a microprocessor that monitors the
quality of the supply and reacts to fluctuations. A voltage
compensation circuit is enabled to boost or reduce the supply
voltage to compensate for the fluctuations. The main advantage
of this topology is that it enables compensation of under and
overvoltage without using the batteries.
Double conversion topology (on-line) is a basis for UPSs
designed for continuous power protection of critical equipment
against all nine power problems: power failure, power sag, power
surge, undervoltage, overvoltage, switching transient, line noise,
frequency variation and harmonic distortion. It ensures a
consistent quality of power supply regardless of disturbances in
the incoming mains. The output voltage is entirely regenerated by
a sequence of AC to DC conversion followed by DC to AC
conversion in order to create power supply without any electrical
interference. Double conversion UPSs can be used with any type
of equipment as there are no transients when changing over to
battery power.
