DESCRIPTION OF BLOCKS
RECTIFIER:
In ARTonPlus Series UPSs, a PWM controlled IGBT rectifier is used to increase input power
factor (PFC) and to decrease input current harmonics (THDI).
The IGBT rectifier accepts 3-phase AC input and produces a dual polarity DC voltage for both supplying
the inverter and charging the batteries.
BATTERIES:
Batteries are used as reserve DC power supply for the Inverter in case of mains failure. In
ARTonPlus Series, batteries are connected in series with a center-tap output to obtain a dual polarity DC
supply.
Batteries are discharged by the inverter during mains failure. The discharged batteries are re-charged by
the IGBT Rectifier on a constant current / constant voltage basis, if AC mains power is available.
