A control system and method for controlling an inverter used in an electric vehicle. The control system and method measures an average DC bus voltage and compares it to low voltage and high voltage thresholds defining predetermined conditions. If the voltage conditions are satisfied, the six-step mode is enabled based upon an applied torque command. Thus, if the torque command is higher than a high torque threshold, the six-step mode indefinitely enabled, and if the torque command is below the high torque threshold, the six-step mode is enabled for a limited time duration, and then disabled.
