Electric Propulsion

Ion Thruster


Airbus Crisa has a huge experience in electric propulsion power processing units design and development covering from 700V to 2.2kV gridded ion thrusters thanks to its flight proven high voltage technology. Power processing cutting edge technology provides up to 6 kW to all the power supplies required for thruster operation like neutralizer, keeper, ignition, radio frequency generator and flow control system.
Thruster control, fault and parameters configuration are provided as well.
Thanks to the modular approach, units easily adapts to the electrical propulsion system’s needs.
