Abstract
A system and method for controlling a DC midpoint terminal voltage of a three level inverter is provided. The method includes receiving an input power signal at a three level motor control system that includes a three level inverter, the three level inverter powering an electric motor, determining, in the three level motor control system, a speed value of the electric motor, and adjusting a zero-sequence inverter output voltage to adjust a midpoint voltage at the DC midpoint based on the determined speed value.
