Power supply for aircraft
Aircraft power is 400Hz power; while the aircraft is operating, power is generated by the generator on the aircraft. However, once it lands, the aircraft cannot keep its engine running to supply power to itself while on the ground. The frequency converter supplies power to the aircraft throughout the time it is parked at the airport. The main fields using this are the Navy, the Air Force, and civil aviation
Power supply for Radar (Testing and Operating)
Radar and ground transmission systems both use a 400Hz power source. The main fields using radar are military and telecommunications.
Power supply for missile systems
Missiles and related systems.
