Patent ID: 7148649

Claim:
A hybrid-electric vehicle (HEV) comprising: a prime mover; a matched reactance machine integrated with the prime mover; a power conditioning unit receiving three-phase power from the matched reactance machine, wherein the power conditioning unit is a three-phase bridge rectifier using six diodes without using semiconductor switches; and a control unit for controlling a speed of the matched reactance machine to provide a substantially constant terminal voltage for a variable demand level; wherein: the matched reactance machine comprises a permanent magnet rotor type machine having a back electromotive force (BEMF) voltage with a line-to-line peak voltage that is equal to a desired terminal voltage of the matched reactance machine at a first finite machine speed; and the matched reactance machine having an inductance value which allows for a proportional increase in the selected BEMF voltage value throughout a speed range between the first machine speed and a second machine speed which second machine speed is greater than the first speed.
