PPU-1500 Power Processing Unit
Power processing unit for 1.5 kW-class electric propulsion systems.
Description
The PPU-1500 converts onboard satellite power and controls operation of electric propulsion subsystems such as the ST-100 thruster and xenon feed system. The lab model has demonstrated strong performance with Hall thrusters up to 1.5 kW, and an engineering model is in development for flight qualification. The architecture is designed for future transition to radiation-hardened components without redesign, suitable for LEO through MEO/GEO and deep space missions.
