Abstract
A system for mitigating a solid state power controller (SSPC) open or closed state change caused by single event latchup (SEL) includes an ON circuit, an OFF circuit operatively connected in parallel to the ON circuit, a holding capacitor operatively connected in parallel with the ON circuit and the OFF circuit, and a power switching device operatively connected to the holding capacitor and the ON circuit. The system is configured to maintain, during and after the SEL, a drive state voltage to the power switching device that is stored in the holding capacitor prior to the SEL.
