The invention belongs to the field of aircraft electromagnetic compatibility design, and relates to an aircraft high-temperature area electromagnetic interference suppression method and device. The invention provides an electromagnetic compatibility design method, which comprises the following steps of: performing regional electromagnetic compatibility protection design on equipment in a high-temperature region on an airplane according to a mounting region and a design characteristic, and arranging a regional electromagnetic interference suppression device at an equipment power supply front end in the same region, wherein the regional electromagnetic interference suppression device is composed of a lightning suppression module and a power supply filtering module. The problem that the electromagnetic compatibility design of airborne equipment cannot be effectively implemented due to the fact that electronic components are not resistant to high temperature in a high-temperature area canbe solved, the electromagnetic interference suppression design of the equipment in an airplane area is simplified, the system weight is reduced, and the development cost is reduced.

    本发明属于飞机电磁兼容性设计领域,涉及一种飞机高温区电磁干扰抑制方法及装置。本发明提出一个电磁兼容设计方法,将飞机上高温区域内的设备按照安装区域和设计特征进行区域电磁兼容防护设计,通过将位于同一区域内的设备供电前端设置区域电磁干扰抑制装置,该区域电磁干扰抑制装置由雷电抑制模块和电源滤波模块组成。本发明能够解决高温区域内因电子元器件不耐高温而无法有效实施机载设备电磁兼容性设计的问题,简化飞机区域内设备电磁干扰抑制设计,减轻系统重量,降低研制成本。
