In this paper a complete model of aircraft electrical system is simulated and analyzed using 24-pulse techniques in power conversion. The classical aircraft electrical system is described in thispaper. The performance characteristics of 24-pulse converters are studied with differentconditions of operation and the simulated model is tested with different jet engine speed whichyields to different frequencies of operation from 400Hz to 1200 Hz. The simulated system isdescribed and analyzed in two sections; Generating-Rectifying and Inverting unit. In order tomatch the practical condition, different types of load are considered here such as; constantpower load, constant voltage load, constant current load, passive and dynamic load. Thevoltage and current for the generator side and inverter side are recorded and the total harmonicdistortion (THD) is calculated for different conditions of operation. The obtained results arecompared with conventional 6-pulse converters which are used in classical aircraft electricalpower system. The proposed system is simulated and analyzed using the PSIM 9 softwarepackage with analysis completed in MATLAB 2010.
