3. Functional Block
As a true online UPS, the product applies a double conversion topology, comprising functional blocks as
shown in Figure 3.1
Figure 3.1 Function block Diagram
The CNTL block controls the action of the UPS system. It also provides the communication interface for
receiving and executing command from users via the panel or other communication protocol. When the
UPS becomes abnormal, in most case, the CNTL can provide basic information indicating the status of
the UPS.
The Rectifier and PFC blocks are the input stage of the UPS. The blocks convert AC input power into
two stable DC power stored in the BUS capacitor. In the meantime, PFC (Power Factor Correction) will
be executed and allows input current tracking the input voltage waveform. Therefore, the input power
factor will be corrected to 1 to achieve maximum efficiency and produce lowest power pollution to the
utility.
The PFC block in battery mode, also called Booster, is used to convert the low voltage DC power to
higher voltage with stable DC power, stored in the BUS capacitor.
The Inverter block is the output stage of the UPS and used to convert DC power from the BUS capacitor
to sine waveform output power.
When the utility is within the acceptable range, the UPS will provide power directly from the utility input
and the Rectifier and PFC will be executed at the same time.When the utility is outside of the acceptable
range, no matter it’s because of input voltage or input frequency, the UPS will shut down the Rectifier
and PFC functions and turn on the Battery Booster. In case of sudden interruption from input utility, the
controller can detect the interruption in very short time. During the short interval of detecting the
interruption, the output power will be provided by the power stored in the BUS capacitor. In this way,
there is no any interruption on output power.
The charger charges the battery when the UPS system is in online model. You can set the current from
1A to 4A by changing the jumper. And you also can choose a different voltage corresponding to different
battery pieces by changing the jumper on the CNTL board and the charger board.
The Input EMI section provides EMI filter function. The input EMI filters can prevent the UPS from being
interference by external electronic/magnetic noise which is generated by other electronic system and

8
prevent other systems from the noise generated inside the UPS system.
The SPS generates DC power supply needed by operation of the circuit of the UPS itself. The Bypass
provides a path that utility can power the output directly when the Inverter is not executed. The
Maintenance Bypass provides another path that utility can power the output directly when UPS is in
maintenance status.

4. Working Principle of the Major Functional Block
4.1 Switch Power Supply
The Switch Power Supply (SPS) supplies DC power for UPS operation. The input source of the SPS is
the grid when the grid voltage is higher than 110V . Or the input source of the SPS is the battery.
Figure 4.1 Basic circuit of power supply
Figure 4.1 is a flyback converter. When Q1 is on, all rectifier diodes (D1/D2/D3) are on open status and
all output capacitors (C1/C2/C3) supply currents to the load. The primary coil of the transformer will
become a pure inductor and the primary current will linearly increase to store energy in the coil. When
Q1 is off, primary current will stop and all rectifier diodes (D1/D2/D3) will turn to “close”status. It will
release the stored energy from the primary coil of the transformer to the secondary coil to supply loads.
At the same time, it will charge output capacitors including 15V, +12V, +5V, +12V(Fan), and HFPW.
The power of 12V, +5V supplies stable voltage to all kinds of ICs and other devices such as HCT. The
+12V (Fan) is supplied to fans and relays. The HFPWsupplies a high frequency power for the switch
(SCR/IGBT) driver and some other drive boards.

Figure 4.2 PFC/Booster
As shown in the Figure 4.2, when Q1/Q2 is on and D1/D2 is off, the current will increase to store energy
in choke(L1/L2). When the Q1/Q2 is off and D1/D2 is on, the choke will release energy. Therefore, we
can control the current in chokes (input current) by regulating the time of Q1/Q2 on and off.
4.3 Inverter
The input of the three level inverter topology is two DC voltages, and the output is an AC voltage, as
shown in the Figure 4.3. When Q1/Q2 is on and Q/Q3 is off, the voltage of the bridge midpoint is +BUS.
When Q1/Q2 is off and Q3/Q4 is on, the voltage of the midpoint bridge is –BUS. We can get any voltage
waveform between ±BUS voltage from LC filter output by regulating the duty cycle of Q1/Q2/Q3/Q4,
including sine wave form.

Figure 4.3 Three level inverter bridge
4.4 Charger
The function of charger is to charge and maintain the batteries at fully charged condition. The charger
charges the batteries with a constant current at initial stage. At the same time, the battery voltage keeps
increasing until reaching the constant charge voltage point. Then, the charge current will decrease
accordingly, now it’s in second stage. After one hour of constant voltage charging, the charge voltage will
change to floating charge voltage, in general, the charger will control the output voltage at a constant
level (13.65V±1% per battery) to optimize battery recharge time and prolong the lifetime of batteries
without overcharging.

Note: There are two kinds of chargers for standard model UPS and long-run model UPS. They both
apply the same principle, but there is on difference in charger output capacity.

5.1 SPS-Charger board (Power Stage Board)
The PSDR board consists of SPS. It gives the whole UPS system power supply.
You can set the current from 1A to 4A by changing the jumper. And you also can choose a different
voltage corresponding to different battery pieces by changing the jumper on the CNTL board and the
Charger-Charger board. The charge voltage is controlled by CNTL board.
5.2 CNTL board (Control Board)
The CNTL board is the core of the UPS system. It controls the actions of the semiconductors and other
mechanical switches, the display of the LED/LCD, the sound of the buzzer, the communication with the
computer, and other important tasks.
5.3 Communication board
The Communication board provides RS232/USB interface to the users, and it also provide one EPO port
to cut off the output immediately.
5.4 EMI board
The EMI board can prevent the UPS from external electronic/magnetic noise generated by other
electronic systems, and also prevent other systems from the noise generated inside of the UPS system.
And the MOV is also on the EMI board which can absorb the surge to protect the UPS system.
5.5 Main Power board
The Main Power board is the most expensive and biggest PCB in the UPS. It converts the AC/DC power
to a pure sine waveform. And then it converts the DC/AC power. There are many semiconductors and
easy-failure components on the board, so it’s required to pay more attention when UPS is abnormal.
5.6 Para(A) and Para(B) board
The Para(A) board and Para(B) board is used for parallel communication when the UPS system is

12
running in parallel mode.
5.7 O/P Relay board
The O/P Relay board should be installed for parallel system. For single system, it can be removed.
The board can disconnect the UPS from the output (parallel system).
