Abstract
An inverter circuit electrically connects between a high-voltage bus and a multi-phase electric machine, including a plurality of switch pairs. Each switch pair includes a first switch electrically connected in series with a second switch at a node. Each node electrically connects to a phase of the multi-phase electric machine with the first switch electrically connected between a positive side of the high-voltage bus and the node and the second switch electrically connected between a negative side of the high-voltage bus and the node. The first switch is configured as a normally-OFF switch. The second switch is configured as a normally-ON switch.
