MODERN AIRCRAFT ELECTRONIC POWER CONVERTERS

Abstract

The article points out to changes in on-board aircraft power converters, which are necessary due to weight reduction and improvement of reliability and maintenance. The paper presents the evolution from old rotary converters to modern solid state converters and describes their advantages. There is also the mention about electro-magnetic interference (EMI), which is introduce during the conversion and how could it be reduced for different types of converters. The operational principle of various power inverters is simulated in MATLAB to figure out different output waveforms quality which could be reached by such a conversion.
