An Analytical approach for estimation of EMC performance of Electro Explosive Device (EED) package

Abstract

In a spacecraft, the Electro Explosive Devices (EED) are used for the appendages deployment activities like Antennas Deployment, Solar arrays deployment etc. EED electronics package provides the required excitation to fire the SQUIB. During the launch phase, the spacecraft experiences a high level of Electromagnetic (EM) radiation. The EEDs should not get enabled due to the EM radiation. EMC analysis was carried out on EED package to assess the safety margin for the squibs, when it is subjected to the radiated E-fields and conducted noise. Micro-cap and CST cable studio software's are used to simulate conducted susceptibility and radiated susceptibility EMC margins respectively.
