The ISIS Electrical Power System (iEPS) is the second-generation compact power system for nanosatellites, ideal for 1U up to 3U CubeSats. The system leverages wide bandgap semiconductor technologies, implementing GaN-FETs to improve solar power conversion efficiency and performance. It is equipped with an integrated heater, hardware-based Maximum Power Point Tracking (MPPT) and hardware voltage and over-current protection. The iEPS provides 3.3V and 5 V regulated buses, as well as an unregulated bus. An add-on daughter board allows additional configurations to suitably power the system and payload instruments.
