Requirements for power supply reliability are growing due to the increasing application of computer systems and data carriers, word processing, automated production processes and complex data networks.

Function

.

The static inverter not only has the task of continuously supplying the connected consumers without interruption, but it also has to provide an improvement in the quality of the voltage and frequency in relation to the standard supply. In normal operation the consumer is powered by the inverter and the transformer output line.

Static inverters are increasingly being installed for loads that require AC voltages that are not affected by grid interference, for example:

.

• Data processing facilities

• Process control computers

• Facilities for aviation security

• Signaling and alarm systems

• Telecommunications systems

• Food and substations
