1. A hybrid-electric vehicle (HEV) comprising a matched reactance machine power generation system (MRMPGS) wherein:

  • the MRMPGS comprises a permanent magnet rotor type machine having a selected back electromotive force (BEMF) voltage value and a selected machine inductance value;

    the BEMF voltage value is selected having a line-to-line peak voltage that is equal to a desired terminal voltage of the machine at a first machine speed; and

    the machine inductance value is selected based upon a machine reactance value and a frequency value which correspond to a proportional increase in the selected BEMF voltage value between the first machine speed and a second machine speed.
