About
The PPU-200 (Power Processing Unit) is a power management unit specifically engineered for Low Earth Orbit (LEO) satellite applications. Its primary function is to convert onboard electrical power to efficiently supply Hall-effect thrusters operating within the 80–230 W power range. Beyond power conversion, it also provides crucial control over the Xenon Feed System, making it an integral component of the overall electric propulsion system. The unit boasts flight heritage, demonstrating reliable performance in orbit. A key feature is its patented anode power supply architecture, which ensures stable and efficient operation of the thruster while simultaneously optimizing the entire system’s performance. Designed with an emphasis on mass manufacturing, the PPU-200 is optimized for scalable production and seamless integration into satellite constellations, aiming for low system cost and complexity while maintaining reliable and efficient operation.
