Abstract
An inverter system is provided such that the system includes a direct-current (DC) voltage supply, an inverter, an electric machine such as a motor, and a controller coupled with the inverter. The inverter has four or more legs, each with two switches operating complementary to each other. The controller can determine which three of the four or more legs are selected to operate the inverter and uses a remaining one of the four or more legs to operate the inverter by activating/deactivating certain switches during null vector state.
