USE CASES

Air transport, heavy goods vehicles, railways and motor vehicles can all benefit from this technology. Used in generator mode, it could also find a place in the renewable energy sector.

APPLICATIONS

The CTAF concept offers an innovative, multi-source, modular powertrain structure designed to deliver high mechanical power from a low-voltage supply (≈50 V for 100 kW) without compromising efficiency.

ADVANTAGES

There are many advantages to a low-voltage multi-source power supply for each element of the chain:

  • For the battery, it facilitates battery control and increases safety during handling.
  • For the inverter, size and weight are reduced. Conduction and switching losses are also lower.
  • For the electric machine, insulation breakdown is prevented, increasing the motor’s service life.
  • Finally, splitting the power supply improves the system’s resilience in the event of a component failure.
