About
The PPU-500 is a power processing unit specifically engineered for electric propulsion systems in the 500 W class. Its primary function is to provide efficient and reliable power management for Hall-effect thrusters. The unit is composed of three key subsystems: the thruster power module, the xenon feed system power module, and the main controller. The thruster power module is responsible for converting onboard power into stabilized outputs required for the anode and cathodes of the thruster. The xenon feed system (XFS) power module manages low-voltage supplies for various components associated with xenon flow management, including sensors, heaters, valves, and measurement circuits. The main controller is the brain of the system, executing operating algorithms, managing all power converters and system measurements, and facilitating communication with the onboard computer. This comprehensive design enables fully autonomous and reliable system operation, crucial for demanding space missions.
