3 GENERAL UPS DESCRIPTION
3.1 TYPOLOGY
The UPS systems described in this manual are on-line, double conversion; the inverter included
in the UPS always supplies energy to the load, whether mains is available or not (according to
the battery autonomy time).
This configuration guarantees the best service to the User, as it supplies clean power
uninterruptedly, ensuring voltage and frequency stabilization at nominal value. Thanks to the
double conversion, it makes the load completely immune from micro-interruptions and from
excessive mains variations, and prevents damage to critical loads (Computer - Instrumentation -
Scientific equipment etc.).
Output voltage present
The line connected to the UPS output is energized even during mains failure,
therefore in compliance with the prescriptions of IEC EN62040-1-2, the installer will
have to identify the line or the plugs supplied by the UPS making the User aware of
this fact.
Picture 1 – Block diagram
The UPS uses IGBT technology with a high switching frequency in order to allow a low
distortion of the current re-injected into the supply line, as well as high quality and stability of
output voltage. The components used assure high reliability, very high efficiency and
maintenance easiness.
3.2 SYSTEM DESCRIPTION
3.2.1 Rectifier
It converts the three-phase voltage of the AC mains into continuous DC voltage using a three-
phase fully-controlled IGBT bridge with a low harmonic absorption.
The control electronics uses a microprocessor of latest generation that allows to reduce the
distortion of the current absorbed by mains (THDi) to less than 5%. This ensures that the
rectifier does not distort the supply mains, with regard to the other loads. It also avoids cable
overheating due to the harmonics circulation.
