Tame-Power: DC DC converter manufacturer for aeronautics

Power conversion solutions for low-carbon aeronautical mobility


Towards a new aeronautical mobility...

Motivated by the demand to optimize aircraft performance, reduce operating and maintenance costs, increase reliability and reduce gas emissions, the aeronautics and aerospace industry is moving towards more electric mobility solutions. 

The aeronautics and aerospace mobility markets can be broken down into the following sub-markets:

  • Aerospace transport solutions: passenger aircraft, business aircraft, commercial aircraft, military aircraft, airships, etc.
  • New flying objects: drones, flying cabs, etc.

Two major trends are shaping the aeronautical mobility market of tomorrow:

The development of new modes of transportation and the willingness to reach a carbon-free mobility led Tame-Power to adress the electric aeronautics mobility market. Tame-Power falls within the global electrification and energy transition  and brings more environmentally friendly power electronics solutions.

  • Integrate several control modes in input or in output: current, voltage and power
  • Integrate a specific mode to battery charge
  • Combine several DC DC converters to increase the total output power 

Tame-Power products are designed for stationary or embedded applications in the aerospace mobility market and are integrated into:

  • On-board applications: aircraft (passenger, business, commercial or military), airships, flying cabs and common avionics loads.
  • Stationary applications: charging solutions.


For specific requests, Tame-Power offers to adjust its references in order to provide you with DC-DC converters that :

  • Meet your specific needs based on catalog products,
  • Allow you to optimize your planning constraints at controlled costs.

Tame-Power is experienced in custom developments and has many technological bricks in power electronics (insulation, filtering, conversion, dissipation, packaging, control and monitoring ...) that can be adapted to a specific product.

Customized DC DC converters

Tame-Power supports its customers in the development of custom converters throughout the product life cycle: from the definition of the electrical architecture to the support of the product integration. Tame-Power offers to design and produce specific DC-DC converters from 1kW to several megawatts and from 35V to 950V.

DC DC converter racks

Tame-Power DCDC converters can be combined in parallel to increase the total power transferred. Thus, Tame-Power proposes to combine up to ten converter modules.

Tame-Power's certifications and accreditations on the aeronautics market

Tame-Power studies solutions that meet the needs of innovation and safety through its expertise in the design of critical aeronautical systems. Thus, Tame-Power's technologies contribute to meeting current and future regulatory requirements, including:

  • MIL-HDBK-217F Notice 2 and FIDES (Reliability Predictions)

    EN 9100

    EN 9100 is a European standard that integrates the principles of ISO 9001 and addresses the entire supply chain of the aerospace and defense industry. EN 9100 is the equivalent of AS9100 (America) and JISQ 9100 (Asia). It certifies the reliability and quality of TRONICO's services for the design and manufacture of embedded products.

      AQAP 2110

      The AQAP 2110 standard is a NATO standard that sets out the requirements for quality. It is a quality management tool that meets the requirements of ISO 9001 and the specific requirements of the "Defense" sector.

        Other standards

        Tame Power is also able to integrate your own constraints to standards specific to your field of application:

        DC DC converters for Stratobus

        The Stratobus project is a geostationary multi-mission platform concept that can carry payloads for civil or military applications (surveillance, observation, detection, communication, etc.). Self-sufficient in energy thanks to its solar panels and its reversible fuel cell, this dirigible balloon evolving in the stratosphere, at 20 km altitude, is propelled by electrical energy. Tame-Power is a partner in the consortium to provide DCDC converters to power the balloon's power, communication and control equipment.
