AbstractThe Solar Probe Plus mission, under NASA’s Living With a Star Program, will fly a spacecraft (S/C) through the sun’s outer corona with orbit perihelia that gradually approach as close as 9.86 solar radii from the center of the sun. The mission will gather data on the processes of coronal heating, solar wind acceleration and production, and evolution and transport of solar energetic particles. The S/C is powered by two actively cooled photovoltaic solar array (S/A) wings. A novel power system electronics (PSE) box facilitates power delivery to the S/C in a tightly packaged, single-fault-tolerant system. The PSE contains a central digital controller to maximize power throughput from the S/A while protecting the battery, S/A, and downstream loads. The PSE is configurable and scalable up to 900-W output power. A novel grounding and isolation scheme is presented with the detailed architecture and digital control implementation.
