Study on emission characteristics of electromagnetic radiation for MEA electric environmental control system
摘要
Abstract
The three⁃phase PWM inverter as the main electromagnetic interference source generated from more electric air⁃craft(MEA)electric environmental control system is analyzed. According to the working principle of the three⁃phase PWM in⁃verter circuit and its simplified circuit,the common mode current causing the electromagnetic interference is obtained by analy⁃sis. The common mode current is taken as the excitation source of the electromagnetic radiation model for the electric environ⁃mental control system to establish the electromagnetic radiation emission model of the MEA electric environmental control sys⁃tem. The electric environmental control system influencing on the electromagnetic environment in the cabin and electromagnetic coupling effect of the cabin cable is studied with 3D electromagnetic simulation software CST. The research results show that the electromagnetic interference generated by electric environmental control system makes the electromagnetic environment deteriora⁃tion within the aircraft,increase the electric field strength of the interference in the cabin and other system crates and induced current of the cabin cable.关键词
