Claim Text:
1. An excitation control circuit for an electrically excited wind power system, comprising: at least one converter arranged between an AC electric grid and a wind power generator so as to convert AC power generated by the wind power generator into AC power corresponding to the AC electric grid; and at least one AC/DC conversion module having an input side and an output side, where the input side of the AC/DC conversion module is electrically connected between the converter and the wind power generator, the output side of the AC/DC conversion module is coupled to an excitation device, and the AC/DC conversion module is used to convert the AC power generated by the wind power generator into a DC voltage so as to provide the excitation current of the wind power generator through the DC voltage, wherein
