An open-end winding induction generation system for frequency insensitive AC loads in more electric aircraft

In more electric aircraft (MEA), supplying constant voltage variable frequency (CVVF) AC power to frequency insensitive loads (eg. wing de-icing system, galleys, etc.) in DC primary distribution system requires an AC-DC-AC conversion which adds losses and additional hardware installment to the system. This paper presents a novel open-end winding induction generation system supplying CVVF AC power for MEA As a subsystem of an AC/DC hybrid generation system, this CVVF induction generation system uses a series connected inverter-load topology without any energy storage device. A current oriented control scheme is used to regulate both AC and DC side voltages of the system without battery compensation. The proposed series connected induction generation system presents reduced hardware footprint compared to conventional shunt connected and battery compensated series connected induction generation system. The performance of the proposed system is demonstrated by simulation in MATLAB/SIMULINK.
