A converter system for coupling to an ac power source includes a rectifier and a bi-directional converter. The rectifier has a first set of terminals inductively coupled to an ac power source and a second set of terminals coupled in series with a series dc bus, and is operable to convert ac power at the first set of terminals to dc power at the second set of terminals. The bi-directional converter has a first set of terminals coupled to the ac power source and a second set of terminals coupled to a parallel bus, and is operable to transfer power from the ac source to the parallel bus in a first operating mode and transfer power from the parallel bus to the series dc bus via the rectifier in a second operating mode. A corresponding power generation network and power transmission method are also provided.
