Abstract: A vehicle includes a gas turbine engine having at least two spools and an associated power system. The power system includes two independent power subsystems, including a first power subsystem for managing power transfer between spools and a second power subsystem for supplying a base power load to the vehicle. The first power subsystem has a first electric machine mechanically coupled with a first spool of the gas turbine engine and a second electric machine mechanically coupled with a second spool. The second electric machine is electrically coupled with the first electric machine such that electrical power is transmittable therebetween. The second power subsystem has a third electric machine mechanically coupled with one of the spools. The third electric machine is electrically coupled with a load positioned offboard the gas turbine engine. The first power subsystem and the second power subsystem are electrically decoupled from one another.

Abstract: Systems and methods related to controlling flux through an inductor of a power converter are described. For example, a control system is configured to control a multi-level converter having a first leg, a second leg, and at least one inductor. The control system includes a processor operatively coupled to a memory. The processor receives a reference signal. The processor determine flux through at least one inductor of a converter. The processor controls a temporal distribution of the flux through the at least one inductor based on the flux through the at least one inductor according to the reference signal.
