Abstract:
1. A power control apparatus, comprising: a first poly-phase AC electric motor including a star-connected first poly-phase winding as a stator winding; a second poly-phase AC electric motor including a star-connected second poly-phase winding as a stator winding; an electric storage charged by regenerative power generated by at least one of said first and second poly-phase AC electric motors; an electric load electrically connected between a first neutral point of said first poly-phase winding and a second neutral point of said second poly-phase winding; and voltage control means for calculating surplus power corresponding to remainder obtained by subtracting power charged in said electric storage from said regenerative power, and for controlling a voltage across said first and second neutral points in accordance with the calculated surplus power.
