A power processing unit (PPU) is a circuit device that convert an electricity input from a utility line into the appropriate voltage and current to be used for the device in question.

The PPU is self-contained, air scrubbing systems designed to provide pressurized and/or recirculated air, free of corrosive gases. It is ideal for removing air contaminants from controlled environments containing sensitive computer electronics and electrical equipment.

The PPU conditions and supplies power to the thruster and propellant flow control (PFC) components. It operates from an input voltage of 24 to 34 VDC to be compatible with typical small spacecraft with 28 V unregulated power systems.

The Power Processing Unit (PPU) is the central component of the Electric propulsion System (EPS). It provides power conditioning and control for Hall Effect Thruster and the Fluidic Management System (Xenon/Krypton).

The pathfinder model (PM) propulsion system consists of the H71M-PM Hall-effect thruster, a breadboard 1-kW power processing unit (PPU), and a propellant flow control system.

ELEKTRO PPU NG2 offers the best compromise between ISP and Thrust. Relying on its modular architecture, it can address any thruster from 1 to 20kW, and a large voltage range of 300V to 600V. The Power Processing Unit (PPU) is the central component of …

Oct 23, 2019 · What does a PPU do? The Phase Four PPU takes DC battery power from your spacecraft and delivers RF energy to the thruster head, which efficiently ionizes the xenon propellant and accelerates...

The Power Processing Unit (PPU) is designed as a part of the Electric Propulsion System (EPS) SPS-40, which consists of ST-40 Hall Thruster and Xenon Feed System (XFS). PPU consists of 3 main subsystems: Thruster and XFS power parts and the main controller.

PPU architecture and operating parameters is critical in achieving the high potential for spacecraft mass reduction obtainable with electric propulsion systems. In order to operate a TAL, the PPU must accomplish the tasks of providing system telemetry, cathode heater power, starter (ignitor)/keeper power

Dec 8, 2021 · The Qualified Power Processing Unit (PPU) is a power management equipment intended for LEO satellite applications and designed according to ESA ECSS standards. It conditions onboard voltage to power a Hall thruster from 100W to 500W and controls xenon propellant feeding system.
