The introduction of EMA Systems requires the use of redundant inverters to drive the EMA and ensure reliability and safety. Redundant converters allow the implementation of fault tolerant control and high quality operation. Fault control has been implemented by means of redundant converter and fault detection system.
There is a general trend in the aerospace industry toward increasing the use of electrically-powered equipment.
