Abstract

With the development of more electric aircraft (MEA), the number of power electronic equipment and variable frequency electrical loads are increasing rapidly, which leads to challenges in terms of power quality of aircraft power system. In this paper, a harmonic current generator (HCG) for MEA power system is designed, which can realize high frequency harmonic current injection (up to 40 times of fundamental frequency, 32kHz for 800Hz power system). For the equivalent switching frequency is close to 1MHz, a GaN HFETs based cascaded Hbridge topology is selected and a frequency adaptive multiharmonic proportional resonance controller is introduced to achieve accurate injection of harmonic currents. To verify the analysis and injection performance of the proposed HCG, the simulation model based on PLECS is developed and tested under various operating conditions. To verify the performance of the proposed HCG, a 10kW experimental prototype is built and tested in the laboratory.
