  "textContent": "A method for control of an alternating current (AC) electric motor through a voltage inverter having a plurality of electric switches with on-off states that collectively define a plurality of non-zero vectors angularly disposed about a common origin includes through one or more controllers, calculating a rotating voltage reference vector to apply to the AC electric motor through the voltage inverter. The method also includes through one or more controllers, calculating voltage inverter switching times using a first subset of the plurality of non-zero vectors, the first subset including fewer than all of the plurality of non-zero vectors and including no adjacent non-zero vectors, to synthesize the rotating voltage reference vector. Additionally, the method includes through the voltage inverter, applying the rotating voltage reference vector to the AC electric motor.",
