The invention relates to a double-port self-excitation double-direct-current output switched reluctance generator converter system. The system comprises eight capacitors, eleven switching tubes, three-phase windings, eight diodes, three inductors and an isolation converter, wherein two paths of output are output through a double-generation loop at the generation stage of each phase winding, and when power is insufficient, a low-voltage output side and an excitation power supply are ensured preferentially, and the sacrifice of a high-voltage output side changes the wider operation range of thesystem. The power generation benefit is improved based on the strengthening of the excitation and broadening of the excitation range, and the dual-path excitation can be achieve by employing a simplestructure and through control. Besides, the staggered high-frequency switch control is employed, the electric energy quality at the high-voltage side is high, the isolation converter achieves isolation and improves the electric energy quality of the low-voltage side; and moreover, the whole system is simple in structure, convenient to regulate and control, various in function, high in adaptabilityand high in power generation benefit, and has a certain application value in the direct current user system in various power generation system fields.
