You can find them at many filling stations: Fully automatic tools to fill up flat tires. You just type in the required air pressure, connect the tube to the car's tire, and press a button. All the rest is done automatically. The compressed air is generated by an electric air pump and stored in a tank. The pump motor is driven by full electronic drive inverters, allowing precise and energy-saving airflow control. Depending on the size and power rating, the compressor is either operated on single-phase or three-phase mains.

Diotec's DIW040F135 is a 40 A / 1350 V IGBT used in the drive inverter circuit. It offers a fast switching characteristic and low saturation voltage, both for saving energy and improving efficiency of the inverter stage. An integrated freewheeling diode helps to save board space and assembly costs. The part comes in standard TO-247 package for easy heat sink mounting and effective cooling.
