Power processing units for electric propulsion systems - PPUs
PPU for GIT
MVPPU for HET and GIT
PPU for GIT
PPU for Gridded Ion thrusters targets full electric geostationary satellites requiring maximum specific impulse. Optimum operational thruster performance can be achieved thanks to the flexible, autonomous and flight proven power management developed by Airbus Crisa for GIT technology.
Features
Main functions:
- Dual mode operation
- High voltage flight proven technology
- Flexibility to accommodate changes in thruster parameters
- Fully autonomous failure detection and recovery
- Flow Control Unit integrated
- Compatible with regulated and unregulated power buses
Key parameters:
- Up to 8 kW @ 1800 V for grids
- Up to 500 W for neutralizer
- Up to 1 kW for radiofrequency power supply
- MIL-STD-1553B communication bus
MVPPU for HET and GIT
Multi-voltage Power Processing Unit is the answer from Airbus Crisa to provide the same performances as the preceding classical PPU but taking into account the highly demanding New Space constraints, thanks to the extensive use of flightworthy COTS parts and fully automated industrial approach.
It is built with fully digital control, GaN based power electronics able to provide unpreceded performances at half the volume.
