About
PureLine Topaz/THORs is a power processing unit (PPU) subsystem developed by Airbus as part of its PureLine range of electric propulsion electronics. It provides an end-to-end solution for satellite electric propulsion in what Airbus describes as its most compact, innovative and flexible design to date. The PureLine series was initially developed for constellation applications requiring large quantities, enabling disruptive unit pricing while maintaining high product quality; this approach has since been extended to global satellite applications. Topaz/THORs is specifically tailored to New Space types of applications and features a design lifetime of 10 years in low Earth orbit (LEO). It incorporates latch-up-free parts and error protection for improved robustness in the space radiation environment. The subsystem is well suited to supporting key electric propulsion maneuvers, including orbit raising, station keeping, and deorbiting. It is offered as part of Airbus’s broader range of power control and power processing electronics for electric propulsion systems, reflecting the company’s position as a leading European supplier of space power solutions.
