Nowadays, we strongly depend on electricity to maintain the proper function of our soci-

ety. 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 bet-

ween 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 continuously constant voltage to 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, provi-

ding 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 management■ Power supply in the hospital field, to operating rooms and intensive

care units

Main component groups:■ Rectifier to generate the DC-link voltage and thus supply the inverter■ Inverter to generate the required voltage at the load■ DC / DC Converter for charging and discharging of the battery system■ Optional stage to boost the voltage to archive sufficient output voltage■ Switch to bypass the UPS in case of overload or system failure

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, 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.

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.
