I. GENERAL DESCRIPTION
1.1 Introduction
ARTonPlus Series Uninterruptible Power Supplies are double-conversion, on-line UPS’s manufactured with
the latest IGBT and PWM technology, to produce an uninterruptible, microprocessor controlled pure sine
wave output to critical loads.
ARTonPlus Series units are 3-phase in/3-phase out devices, and they are installed between a three phase
critical load, and a 3-phase+N mains supply
The advantages of using ARTonPlus Series UPS:
Power blackout protection:
If the mains power fails, the UPS continues to supply the critical load using the energy stored in its
batteries, keeping the load immune from power disturbances.
Increased power quality:
The UPS has its own internal voltage and frequency regulating circuits, which ensure that, its output to
the critical load is maintained within close tolerances, independent of voltage and frequency variations
on the mains power lines.
Increased noise rejection:
By rectifying the input AC power to DC power and then converting it back to AC (Double-Conversion)
any electrical noise present on the input mains supply line is effectively isolated from the UPS output.
Therefore the critical load is supplied with only clean and uninterrupted AC power.

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.

INVERTER: It is manufactured by using the latest IGBT technology and Pulse width Modulation (PWM)
technique. The Inverter converts the DC BUS voltage supplied by the IGBT Rectifier and / or the batteries
into a well regulated 3-phase AC voltage with fixed voltage and frequency.
The output of the inverter is used to supply the critical loads connected to the UPS output.
STATIC TRANSFER SWITCH (STATIC BYPASS) : This is an electronically controlled transfer switch,
which enables the critical load to be connected either to inverter output or to a by-pass power source.
During normal operation, the load is supplied by the inverter output, but in case of an overload it is
automatically transferred to the bypass source without any interruption.
MAINTENANCE BYPASS SWITCH (MBS) : This is a manually controlled mechanical switch, which is
used to supply the critical load, using the bypass source, when the UPS is shut down for maintenance or
troubleshooting purposes.
The load is unprotected against mains supply disturbances and black-outs when it is connected to either
static or maintenance bypass supply.
1.2.1 OPERATING MODES OF UPS
ARTonPlus Series UPSs are capable of operating in various different modes for maximum application
flexibility. These modes are:
-ONLINE mode: This is the normal operation mode for a single UPS. As long as the mains supply is
available and in required tolerances, the load is supplied by the well regulated inverter output and the
batteries are charged at the same time. In case of mains failure, the inverter keeps supplying the load
using the energy stored in the batteries.
-ECONO mode: This is the off-line operation mode for a single UPS. As long as the mains supply is
available and in required tolerances, the load is supplied by the mains supply (bypass supply) via the
Static Bypass Switch of the UPS and the batteries are charged at the same time. During that time
inverter keeps running under no-load conditions and takes over the load in case of a mains supply
(bypass supply) failure, without any interruption. After restoration of the mains supply the load is
transferred back to bypass supply again.
- PARALLEL, REDUNDANT and N+1 REDUNDANT modes are used for parallel operation of two or
more UPS units and will be explained in parallel operation section later in this manual.
When operating in one of the above operating modes, UPS may be in one of the following operating
conditions:
A. Normal Operation (If Mains supply is available):
All fuses and power switches are closed (except the Maintenance Bypass Switch), and the load is
supplied by the Inverter Output. During normal operation, the Rectifier supplies DC power to the Inverter
and charges the Batteries at the same time.
B. Battery Operation :
The Batteries are connected to the Rectifier output. In case of a mains failure (mains power outage or
AC input voltage out of tolerance), the Rectifier stops operating and the DC voltage necessary for the
inverter operation is supplied by the batteries. Therefore the AC voltage output supplying the critical
load is not interrupted, until the batteries are fully discharged. At the end of the discharging time the
Inverter is turned off and it start again automatically, together with the Rectifier, when the mains power
is restored, and the UPS returns o normal operation.
The Rectifier is also turned off and Inverter operates on batteries during automatic or manual battery
test procedure.
C. By-Pass Operation :
If the Inverter output is overloaded or in case of a problem in the UPS, the static switch transfers the
load to the bypass supply without any interruption, provided that the bypass supply is available and
within the tolerated limits.
At the end of the overloading period, if the fault condition is restored, static switch transfers the critical load
again to the inverter output. Note that, during operation from the bypass supply, the critical load may be
effected by any possible disturbances or power failure in the bypass supply.

1.5.2 PFC3P-R1 IGBT RECTIFIER CONTROLLER BOARD:
This electronic controller board is used to control the 3-Phase IGBT Rectifier at the input stage of the
ARTonPlus Series tansformerless Uninterruptible Power Supplies. By using an IGBT rectifier and this
control board, the nput power factor of the UPS is corrected (to 0.99 at full load) and the input current THD
is improved (less than 5% at full load).
A) Basic functions of PFC3P-R1
1. It takes the 3-Phase AC nput voltage and current samples coming to the IGBT rectifier and
generates necessary PWM- IGBT driving signals to correct the input pF and to decrease the input
current distortion (THDI). The signals for the control of each phase is generated independently.
2. It takes the positive and negative DC output voltage samples of the rectifier and adjust the
driving signal pulse widhts to keep these DC voltages constant under normal loading conditions. In case
of overloading of the IGBT rectifier, the rectifier output voltages are decreased to limit the rectifier output
and thus the UPS input current. Different current limiting values for different UPS power ratings can be
set by changing some fixed resistors on PFC3P-R1 board (R63, R124 and R186).
3. In ARTonPlus Series UPSs, the IGBT rectifier produces a dual polarity DC voltage at its output to
supply the transformerless Inverter stage. The batteries which are the reserve energy supply for the
UPS are directly connected to the rectifier outputs again as two separate battery groups with opposite
polarity. The total number of batteries (12V), in a standard ARTonPlus Series UPS, is 60 (30+30). Thirty
batteries are used for one polarity and the other thirty are used for the opposite polarity. The float
charging voltage value for 2X30 batteries is +/- 405V dc. Therefore the no-load output voltage of the
IGBT rectifier is adjusted to +/- 405V (810V dc total).
During normal operation, IGBT rectifier supplies power to the Inverter and charges the batteries at the
same time. PFC3P-R1 board takes the battery current samples and adjusts the IGBT driving signals to
limit the maximum battery charging current to a pre-adjusted safe value suitable for the VA rating of the
batteries. Therefore the output voltages of the rectifier change in accordance with the battery voltages
during the charging period of the batteries.
4. PFC3P-R1 board accepts some control signals from UPS Main Controller Board (P3MC-R5)
and performs the following functions:
-Boost Charge: During boost charge, the rectifier output voltages are increased to the boost
charging voltage level for the batteries and kept at that level until the end of the boost charging
period. At the end of the boost charging period, the rectifier output voltages are decreased to the
float charge level again. The boost charge voltages for positive and negative battery groups are
adjusted separately on PFC3P-R1 board.
-Rectifier Start: When the P3MC-R5 board sends a ‘’Rectifier Start’’ signal to the PFC3P-
R1 board, the input contactor (K1) is energized and the IGBT rectifer starts operating.
-Battery Test: When the P3MC-R5 board sends a ‘’Battery Test’’ signal to the PFC3P-R1
board, the rectifier output voltages are both decreased to a preadjusted value and kept at that level
until the end of the battery test procedure.
5. On the other hand, PFC3P-R1 board sends the following signals to the UPS Main Controller Board:
1. ‘’Rectifier Fault’’
2. ‘’ Positive battery group current sample (either charging or discharging)
3. ‘’ Negative ‘’ ‘’ ‘’ ‘’ ‘’
4. ‘’ Negative battery voltage sample’’

16
B) Adjustments of PFC3P-R1 IGBT Rectifier Controller Board:
-AR1 : Rectifier output voltage with only R-phase operation, (increases CW)
-AR2 : ‘’ ‘’ ‘’ ‘’ “ S-phase ‘’ ‘’
-AR3 : Positive (+) battery group boost charge voltage, (increases CW)
-AR4 : Negative (-) ‘’ ‘’ ‘’ ‘’ ‘’
-AR5 : (+) and (-) battery groups battery test voltage level, (increases CW)
-AR6 : AC input currents THD adjustment,
-AR7 : (-) battery group charging current limit, (increases CW)
-AR8 : (+) ‘’ ‘’ ‘’ ‘’ ‘’ ‘’
-AR9 : Rectifier output voltage with only T-phase operation, (increases CW)
-AR10 : Rectifier negative (-) output voltage, (a single adjustment for equalizing the neg. Output
voltage to the poz. output voltage, increases CW)
-AR11 : Rectifier fault threshold level adjustment.

-TP16 : T-phase, AC input current sample,
D) PFC3P-R1 board ‘’jumper’’ positions
There are various jumper connections on the board which are inserted or removed during testing or normal
operation of the rectifier. Their list and positions are given below:
During normal operation:
JP5=JP8=JP12=JP17 = ‘’1’’ (inserted or short circuited)
JP1=JP2=JP3=JP4=JP6=JP7=JP9=JP10=JP11=JP13=JP14=JP15=JP16=JP18=JP19 = ‘’0’’ (removed)
Note: JP1, JP9 and JP16 are used to start or stop the IGBT rectifier phase by phase. They are used to
enable or disable the rectifier to operate on the desired input phase (or phases). If JP1, for example, is
inserted then the rectifier stops using the R-phase (stops generating driving signals for R-phase) for
generating its DC output. If it is removed then the rectifier starts using R-phase. JP9 and JP16 do the same
for S and T-phases respectively. During rectifier output voltage adjustments, they are removed one by one
to adjust the output voltage when operating on each phase separately.
