2.2. Composition and Functions
The F-
3000 system
is composed of numerous parts as follows,
- Input Transformer
- Rectifier & Battery Charger
- Inverter
- Output Transformer
- Static Switch
- Control Circuitry
- Digital Display
2.2.1. Input Transformer
This transformer is manufactured as H class dry type. The output voltage is
designed to correspond the input voltage of inverter and charging voltage of
battery, and the output current, to sufficiently match the sum of the
charging current and the rated current of inverter.
2.2.2. Rectifier & Battery Charger
This unit includes the thyristor module, heat dissipation board, and many
other components. It will convert input AC power to DC power, supply the
inverter, and simultaneously charge the battery with the best condition
possible.
Also, the filtering circuit composed of reactor and condenser, is employed
to filter out the ripple characteristics contained in the rectified DC power,
in order to yield the best possible DC power.
2.2.3. Inverter
This unit contains IGBT (Insulated Gate Bipolar Transistor) module, heat
dissipation board, rapid firing fuse for the semi-conductor protection and
other relevant component. The high frequency switching and the sine wave
Pulse Width Modulation, are utilized in this unit. The inverter will
revert the DC power obtained from rectifier to PWM AC output, and then the
AC filter will make it very similar to the balanced sinewave AC voltage to
supply the critical load.

CROSS T.E.C www.crossups.com
2.2.4. Output Transformer
The primary lead shall be connected to inverter and the secondary to output
in this isolation transformer. It is specially designed to contain the
reactance and partially serves as output filter.
Also, it minimizes the current harmonics, and maximizes efficiency. The
input and output voltage and frequency are synchronized by phase lock loop
oscillator. The synchronized transfer units are placed at the bypass line
and at the inverter section.
2.2.5. Static Switch
This unit operates as an automatic transfer device between inverter and
bypass feed. At the moment of detection of any abnormal operation in
inverter or over-load condition, the static switch will simultaneously
transfer the power supply to bypass feed (commercial power), not to
interrupt the load operation. When the inverter operation returns to
normal, the static switch will then retransfer supply line to inverter,
again without any interruption.
In order to avoid the possible rush current evolved from the phase difference,
this unit is constituted with only semi-conductors.
2.2.6. Control Circuitry
This unit consists of inverter control, alarming circuit, static switch
control, and etc. It is designed to operate though the internal unexpected
voltage transient intervenes. Its power comes from the battery by DC/DC
converter, and thus, power outage or start-up peak current would not affect
the control circuitry operation.

2.3. Operation
2.3.1. Normal
The rectifier and charger will get the AC commercial power and convert it to
DC, and then, send it to inverter for the reverse to AC and to battery
for charging. The filtered AC power from inverter will be supplied to the
load without interruption.
2.3.2. Power Outage
When commercial power fails, the battery starts to let out the reserved
DC power to inverter and it continues to feed the load during the power outage
for the defined time period.
2.3.3. Power Recovery
When the commercial power is recovered, the battery stops to feed and starts
to recharge. At the same time, the commercial power passes through the
normal routine.
2.3.4. Internal Failure & Over-load
The output voltage and frequency of inverter are synchronized with the
commercial power supply at all times. Thus, in case of internal
failure or over-load, the static switch transfers power to bypass feed and
the synchronized power is constantly fed to the load.
