PERFORMANCE EVALUATION OF MULTILEVEL SHUNT ACTIVE POWER FILTER USING FUZZY PI CONTROL FOR AIRCRAFT POWER UTILITY

Abstract
The implementation of electric power in aircraft system increases the use of different kinds of power electronic converters such as AC/DC rectifiers, DC/AC inverters and DC/DC choppers in the system. The incursion of numerous power electronic devices leads to complex network and also causes power quality and stability issues. The current harmonics may cause unbalance in the aircraft electric power system and severe voltage distortion. Thus, the active filters can compensate the harmonics, improves the power factor and work as a reactive power compensator, thus in turn afford power quality enhancement of the system. This work proposes the use of a five level cascaded H-bridge VSI with an improved current control and a suitably developed modulation strategy to reduce harmonics in air craft system.
