Power converter-based aircraft starting/generating system emulator

In order to optimize aircraft performance and decrease operating and maintenance costs, traditional aircraft is moving towards a more electric aircraft. Moreover, integrated starting/generating system is one of the key components in a more electric aircraft. To determine whether starting/generating system meets the intended requirements, it is necessary to test the system. Herein, this paper is going to present a power converter-based test platform to replace traditional test benches for the considerations of flexibility, costs and safety. Firstly, applications and advantages of power converter-based test platform are illustrated. Secondly, the structure of power converter-based starting/generating system emulator is proposed. Next, operating principle of the emulator is comprehensively illustrated. Finally, MATLAB/Simulink based simulation model is build up to evaluate the proposed power electronics emulator for both starting and generating performance. The simulation results can support the working principle of the power electronics emulator and could be used for prototype development.
