A direct-boost double-fed switched reluctance generator converter system, structurally composed of a battery, twelve switch tubes, three-phase windings, thirteen capacitors, twelve diodes, a transformer, and two inductors, each proposed The two branch windings of the phase winding are respectively excited by different excitation power sources and control modes, and obtain enhanced excitation effects. Under the self-excitation power generation structure, high voltage can be directly output, which adapts to the demand for high voltage in most occasions and reduces links. At the same time, this structure reserves a mode that is suitable for the continuous current of the phase winding current in the whole domain, which has strong adaptability, the battery is automatically charged and has high quality, and at the same time, it can feed back energy, so that the power generation system can work normally under extreme conditions on the load side and help the load side to ride through faults. Based on the above functions, the whole system realizes common ground and no power frequency transformer; the invention is applicable to the application field of all kinds of small and medium power high-speed switched reluctance generator systems with various power input and output sides as loads or power grids.
