Abstract:The development of a fuel cell electric range extender for the battery electric Pipistrel Velis Electro by NLR resulted in the question if it is possible to distribute the power of the fuel cell and battery energy storage systems and the electric motor of the aircraft with a single dual-DC-port inverter. A conventional system architecture was used as a benchmark to compare a number of dual-DC-port inverter architecture on some significant characteristics found in simulations. The multi-source inverter showed to be the most promising dual-DC-port inverter architecture for this application. To properly operate the multi-source inverter a multi-objective vector modulation algorithm was required. This algorithm was based on existing strategies with a novel addition that allows the system to operate more efficiently when the motor is operated with a low power factor. The multi-source inverter and multi-objective vector modulation algorithm were studied more thoroughly with an experimental setup that emulated the energy storage systems and engine. After some initial challenges were mitigated, the experimental data supported the simulated results. The multi-source inverter was shown to be a viable alternative to the benchmark system architecture and this project showed the potential of the multi-source inverter in fuel cell electric aircraft.
