POWER SOLUTIONS FOR AIRPORTS

When on the ground, an aircraft cannot use power from the 50Hz/60Hz grid. The aircraft must use 400Hz power supplied by a Ground Power Unit to supply the loads and guidance systems, converted by a frequency converter from 380V/50Hz to 400Hz, with aircraft voltage of 200V/208V/115V.
The frequency converter can be an Outdoor type installed outdoors to meet harsh conditions, or an Indoor type installed indoors, beneath the walkway leading to the aircraft. The indoor frequency converter can also supply power for aircraft maintenance, aviation equipment, and avionics equipment.

Main benefits of using a frequency converter this is energy saving. Ground power units using a 400Hz frequency converter can be switched on whenever power needs to be drawn from the 50Hz ground power grid, meaning there is no need to keep running the aircraft engine and the onboard generator (APU). Therefore, the 400Hz frequency converter minimizes noise (since the aircraft engine is not running), reduces environmental pollution and fuel consumption, and reduces maintenance of the AHU, generator, and batteries on the aircraft

The frequency converter (frequency converter) can be single-phase or three-phase, with the function of converting the mains grid frequency from 50Hz/60Hz to 400Hz for aircraft, aviation equipment, aircraft navigation systems, radar systems, telecommunications systems....
