ABSTRACT:
A vehicular electric power system is composed of a rotating AC machine having polyphase armature coils, a full-wave rectifier for rectifying the generated voltages by a plurality of SiC-MOSFETs to give a rectified output to the battery unit, and a control device for selectively turning on the plurality of SiC-MOSFETs to raise the generated voltages by short-circuiting and open-circuiting the armature coils on the basis of the phases of voltages generated by the rotating AC machine at a predetermined duty factor.
