POWER CONVERTERS

A power converter (100) includes a first set (102) of transistors electrically connected in series, a second set (104) of transistors electrically connected in series, and an AC link (108). The second set of transistors is electrically connected in parallel with the first set of transistors to form an H-bridge (110). The AC link is electrically connected between the first and second sets of transistors. A plurality of H-bridges are connected in parallel and a three-wire DC bus is electrically connected to the H-bridges.
