1. A vehicle comprising:
a source of direct current (DC) power;
a DC voltage bus coupled to the source of DC power and configured to transmit DC voltage generated by the source of DC power;
a power converter coupled to the DC voltage bus, wherein the power converter comprises a semiconductor switching matrix including a plurality of semiconductor switching elements configured to convert the DC voltage to three-phase electric power;
an electric motor coupled to the power converter and configured to receive the three-phase electric power, thereby generating a torque at an output shaft of the electric motor;
a commutator configured to receive a three-phase commutation feedback signal from the electric motor, and responsively generate respective activation signals for the plurality of semiconductor switching elements of the power converter; and
a wheel coupled to the output shaft of the electric motor and configured to be driven by the torque generated at the output shaft of the electric motor.
