Abstract

This article focuses on assessing and improving the survivability of an aero-engine fuel control system under intense electromagnetic pulses (EMPs). Using bulk current injection (BCI) testing combined with numerical simulation, the study identifies the electromagnetic susceptibility of the control system's power module, particularly the voltage regulator chips, which exhibit abnormal output under high-frequency and high-amplitude pulse interference. A protection design method based on field-circuit coordination is proposed, involving the addition of a front-end protection circuit on the printed circuit board to stabilize the power supply voltage and reduce electromagnetic sensitivity without significantly altering the original circuit. The results demonstrate that this approach effectively mitigates EMP-induced disturbances, enhancing the control system's reliability in complex electromagnetic environments.
