Claim:
1. A power converter comprising: a first set of transistors electrically connected in series; a second set of transistors electrically connected in series, wherein the second set of transistors is electrically connected in parallel with the first set of transistors to form an H-bridge; a three-wire DC bus electrically connected in parallel to the H-bridge; a bi-directional AC link electrically connected between the first and second sets of transistors; and a DC bus electrically connected to a battery and a DC bus of a second power converter, the second power converter being electrically connected to a generator, wherein the first and second sets of transistors each form respective 3-level phase legs and the first and second sets of transistors are operated to output a five-level phase voltage waveform from the AC link, and wherein at least one terminal of the AC link electrically connects the H-bridge to an isolated AC machine phase winding.
