Electric power system for a vehicle

A vehicle electric power system comprising:

• a gas turbine engine comprising a low pressure turbine and a low pressure compressor rotatable with one another through a low pressure shaft and a high pressure turbine and a high pressure compressor rotatable with one another through a high pressure shaft;
• an LP electric machine that is rotatable with the low pressure shaft, wherein the LP electric machine comprises a passive rectifier assembly for providing a first power flow;
• an HP electric machine that is rotatable with the high pressure shaft, wherein the HP electric machine is coupled to an active rectifier assembly for providing a second power flow.

A vehicle electric power system comprising:

• at least one electric machine comprising a plurality of tooth-wound multi-phase windings that are substantially magnetically decoupled, wherein the at least one electric machine is mechanically balanced even if one of the plurality of windings is de-energized;
• one or more power rectifiers for producing rectified power from the power generated by the at least one electric machine;
• a plurality of electrical power busses formed after the at least one power rectifier, the plurality of electrical power busses configured to provide DC power to one or more loads within a vehicle.
