Control of a three-sources-power-net for More Electric Aircraft application including a fuel-cell-APU

In this paper a power net for More Electric Aircraft application with three power sources is presented. In extension to the Two-Generators-Concept where two synchronous generators are mounted on one turbine a fuel cell APU is connected in parallel to the 270 VDC power net. The aim is to control the power of the two generators and the fuel cell in order to obtain a stable voltage on the power net busbar.
