Dependance on electricity
Nowadays, we strongly depend on electricity to maintain the proper function
of our society. Blackouts can cause serious consequences.
In developing countries such as China and India, the grid is still very unstable.
Several blackouts and disturbances during the day are not unusual.
Even in highly developed countries such as Germany, there is an average of ­
100 mains failures per year lasting less than 20 ms and about 30 failures
lasting between 20 ms and 1 s.
Uninterruptible power supply (UPS) systems support the user in achieving
­reliable power supply. They compensate, independently of the quality of
mains supply, voltage fluctuations and short-term power failures.
A reliable voltage supply for critical applications is therefore guaranteed.

Power availability and quality
UPS systems ensure a controlled flow of energy to application. They protect
critical operating equipment that is vulnerable to any loss of power. They
­guarantee the power supply to the devices in case the main power fails for a
certain length of time, or if it is briefly interrupted. UPS systems at the same
time protect sensitive equipment, providing a filter function and shield it from
voltage distortions and fluctuations in frequency or amplitude.
UPS systems are in use in many areas, including
„„ Telecommunications
„„ Data centers
„„ Process supply in the chemical and petrochemical industries
„„ Aviation, air traffic control, traffic manqagement
„„ Power supply in the hospital field, to operating rooms and intensive
care units

High efficiency – a key feature
Infineon‘s product portfolio includes components for highest energy
efficiency. Trench gate structure and field stop concept in IGBT technology
have improved the ­performance of power semiconductors in both
switching- and forward losses.
Built into newly developed 3-Level modules in EconoPACK™ 4, EasyPACK 1B
and EasyPACK 2B, and also now in EconoDual™ 3, this topology in
combination with highly efficient IGBT technology, helps to increase the
efficiency of the whole UPS converter system. It also leads to higher power
density and improves the reliability. Optimized 3-level topologies, regarding
switching frequencies are available.
Infineon’s HighSpeed 3 IGBT provides a good compromise between switching
and conduction losses which helps to increase the efficiency in a very smooth
dynamic behavior which improves EMC and radiated noise.
The new TRENCHSTOP™ 5 allows an additional dramatic improvement in both
switching and conduction losses, whilst providing a breakthrough voltage of
650V. This technology is optimized in terms of efficiency for hard switching
applications.
