Airbus Crisa’s power electronic units play a key role in reliable single-failure tolerant management of spacecraft energy sources while providing power distribution protection for the platform and its onboard payload equipment.
During the past two decades, numerous spacecraft have been equipped with Airbus Crisa’s power conditioning units, covering a wide variety of mission scenarios for Earth observation, space science, telecommunications and interplanetary missions.
Power Management and Distribution
Airbus Crisa has a highly successful track record in power conversion and distribution, covering a range of regulated and unregulated primary/secondary power buses from 28 V to 120 V, with power levels higher than 20 kW.
Within its product portfolio covering the requirements of any state-of-the-art spacecraft, Airbus Crisa provides battery charge and discharge regulators, battery management systems, solar array regulators for both direct energy transfer or maximum power point tracking, secondary power conversion, switched and protected power distribution, heater control and reliable deployment chains.
In scenarios where failure is not an option, Airbus Crisa is a leader in the design and development of electrical power subsystems for space exploration and human spaceflight.
The company’s experienced technical staff – combined with the expertise gained in the design of power equipment for challenging solar system probes – have provided Airbus Crisa with a solid basis for system-facing architectures with multiple redundancies as well as autonomous failure isolation and recovery capabilities.
Power for Active Antenna
Airbus Crisa is one of the leading developers of centralized power supply units for DC power solutions with active antennas.
Its unique centralized power and distribution solutions enable hundreds of amplifiers to be supplied via protecting elements with clean DC power – meeting the most demanding RF performance requirements.
With Airbus Crisa’s modular approach, centralized power supply units can cover a wide output power range from 1 kW to more than 10 kW, and are capable of being powered directly from the platform power bus.
Airbus Crisa’s extensive experience in the design and development of electric propulsion power processing units covers the range of gridded ion thrusters from 700 V to 2.2 kV, backed by flight-proven high-voltage technology.
Cutting-edge power processing technology from Airbus Crisa delivers up to 6 kW to all power supplies required for thruster operation, including neutralizer, station-keeping, ignition, radio frequency generation and flow control. Thruster control, fault and parameter configuration are provided as well.
As a result of Airbus Crisa’s modular approach, its power processing units are easily adaptable to the spacecraft’s electrical propulsion system needs.
