High-voltage components are single points of failure that can lead to the malfunction of an entire satellite, making their reliability crucial for the safe operation of satellites in orbit. The discharge phenomenon of high-voltage components caused by charging and discharging has become a bottleneck problem restricting the development and safe use of satellites. As an important energy component of spacecraft, space solar arrays are vulnerable to strong external electromagnetic pulse in future confrontation. When exposed to strong electromagnetic field, the space solar arrays are easily induced to produce discharge damage. To investigate the discharge damage effects induced by strong electromagnetic field coupling in space solar arrays, a three-dimensional electromagnetic model was developed based on the structural dimensions of a typical solar array configuration. By simulating the electric field coupling characteristics and patterns at the triple junction region under different excitation source parameters, we identified the most vulnerable areas prone to discharge and damage on the array surface. The resulting localized strong coupling electric fields provide essential data for subsequent analysis of discharge mechanisms in solar arrays. The research findings provide a valuable reference for the electromagnetic protection design of space solar arrays.
