This presentation discusses and compares the efficiencies achieved in propulsion motors, comparing combustion motors to hybrid, hydrogen and fully electric systems. We then present the Cissoid open inverter platform, based on silicon carbide technology, enabling drive system designers to deliver fast proofs of concept and prototyping while leaving the door open to in-house, tailor-made solutions for the application. We will back up all the marketing claims with simulated, tested and verified results.
