Research on EMI control techniques of airborne power electronic equipment

In the process of high-efficiency control of aircraft, power electronic equipment brings a series of electromagnetic interference problems due to its own electromagnetic characteristics, which makes the electromagnetic environment on the aircraft carrier become worse. Therefore, it must take measures to control the electromagnetic interference. In this paper, the mechanism of electromagnetic interference generation of airborne power electronic equipment is analyzed. And some electromagnetic interference control techniques are proposed from the aspects of anti-interference design and electromagnetic compatibility test which can provide technical guidance for electromagnetic compatibility design and testing of airborne power electronic equipment.
