Claim:
1. A converter system for coupling to an ac power source, the converter system comprising: a rectifier having 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, the rectifier operable to convert ac power at the first set of terminals to dc power at the second set of terminals; and a bi-directional converter having a first set of terminals coupled to the ac power source and a second set of terminals coupled to a parallel bus, the bi-directional converter operable to transfer power diverted from the ac source that has not been injected into the series dc bus 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.
