17. A method, comprising:
transferring electrical power generated by a second electric machine mechanically coupled with a second spool of a gas turbine engine to a first electric machine mechanically coupled with a first spool of the gas turbine engine over an alternating current (AC) electrical system of a vehicle, and
wherein the transferring comprises directing the electrical power from the second electric machine along a second electrical channel to a second AC bus positioned along the second electrical channel, through one or more connections links to a first electrical channel, and to the first electric machine through a first AC bus,
wherein the one or more connection links include an AC converter link for selectively electrically coupling the first AC bus and the second AC bus, the AC converter link including an AC/AC converter, wherein the electrical power generated by the second electric machine is transferred in the AC phase directly between the first electrical channel and the second electrical channel through the AC/AC converter.
