Configuration of inverter switches and machine coils of a permanent magnet machine

摘要

An inverter switch circuit for a permanent magnet machine is provided. Inverter switch circuit has two or more half bridge switch circuits per phase in communication with an equal number of machine coils per phase, of the permanent magnet machine. Each half bridge circuit includes a first and second power switch in electrical series connection. Further, each half bridge circuit is in electrical connection with each machine coil, thereby providing multiple parallel half bridge circuits for each phase.
