1. An electrically powered vehicle comprising:
a first battery, a second battery, and a third battery;
a first inverter coupled to the first battery and configured to generate a first three-phase alternating current (AC) input from power supplied by the first battery, wherein the first three-phase AC input comprises a first first-phase AC input, a second first-phase AC input, and a third first-phase AC input;
a second inverter coupled to the second battery and configured to generate a second three-phase AC input from power supplied by the second battery, wherein the second three-phase AC input comprises a first second-phase AC input, a second second-phase AC input, and a third second-phase AC input;
a third inverter coupled to the third battery and configured to generate a third three-phase AC input from power supplied by the third battery, wherein the third three-phase AC input comprises a first third-phase AC input, a second third-phase AC input, and a third third-phase AC input;
a first interphase transformer configured to generate a first drive phase input from the first first-phase AC input, the first second-phase AC input, and the first third-phase AC input;
a second interphase transformer configured to generate a second drive phase input from the second first-phase AC input, the second second-phase AC input, and the second third-phase AC input;
a third interphase transformer configured to generate a third drive phase input from the third first-phase AC input, the third second-phase AC input, and the third third-phase AC input; and
a three-phase AC motor driven by the first drive phase input, the second drive phase input, and the third drive phase input.
