Abstract
An inverter includes a plurality of inverter legs that each includes first, second, and third switches. A first control line connected to the first switch receives a first control signal. A second control line connected to the second switch receives a second control signal. A third control line connected to the third switch receives the first control signal. The first, second, and third switches are connected sequentially in series. A first connector line is connected between the first switch and the second switch and to a first winding of an electric machine. A second connector line is connected between the second switch and the third switch and to a second winding of the electric machine. The second control signal is complementary to the first control signal.
