Power Systems

Power systems in satellites include the power generation system that harvests energy from the photo-voltaic panels; the Power Conditioning Unit that generates the various power busses and handles battery charging and possibly the propulsion; and the Power Distribution Unit providing power to the various boards and systems of the platform and payloads.

ST’s space portfolio includes a range of Defense Supply Center Columbus (DSCC) JANS and QML Class V (QML-V) and European Space Components Coordination (ESCC) qualified Rad-Hard discrete devices including Schottky diodes and rectifiers, bipolar transistors and power MOSFETs as well as integrated circuits including gate drivers, voltage regulators and integrated current limiters to help develop efficient power systems.
