Abstract

See full text

A turbine generator system includes a doubly-fed alternating-current (AC) generator having a first poly-phase circuit (e.g., a stator circuit) and a second poly-phase circuit (e.g., a rotor circuit), a poly-phase AC-to-AC converter circuit coupled between the first and second poly-phase circuits, a poly-phase transformer having input windings coupled to the first poly-phase circuit and having output windings, and a uni-directional rectifier circuit coupled to the output windings of the poly-phase transformer and configured to convert poly-phase AC from the transformer output windings to direct current (DC).
