Power electronics

Hispano-Suiza, a Safran group company, is a major supplier of power electronics for the engines powering tomorrow’s "more electric" aircraft.

Operating through the Safran Power division, Hispano-Suiza applies its expertise on leading-edge power electronics to a number of products, already in production or under development, including:

  • ETRAS®, the electrical thrust reverser actuation system, used on the A380 nacelles made by fellow group company Aircelle, has now logged over 150,000 hours in flight.
  • EBAC (electrical brake actuation controller), the Boeing 787 braking control unit, produced by fellow group company Messier-Bugatti.
  • EBMA (electrical backup mechanical actuator), developed by Messier-Bugatti to control opening of the A400M landing gear doors.

Supporting "more electric" aircraft

Teaming up with other Safran group companies, Hispano-Suiza is working on the architecture of the electrical systems required for tomorrow’s "more electric" aircraft, with a focus on four areas :

  • propulsion system (engine and nacelle)
  • braking and landing systems
  • electrical flight control actuators
  • electrical power management, from transmission to wiring

POWER ELECTRONICS

With the certification and service entry of the ETRAS® electrical thrust reverser actuation system on the A380 super-jumbo jet (integrated in nacelles and thrust reversers made by Aircelle), Hispano-Suiza is one of the leading producers of power supplies and converters for electrically-driven actuators.
