Abstract：Multi-pulse rectification technique, designed to overcome the high failure ratio of pulse width modulation rectifiers and to improve the low power factor of uncontrollable diode rectifiers, is introduced into wind power system in this paper. Firstly, a new simple structure, high reliability and high power factor twelve-pulse automatic-transformer rectifier is proposed. The operational principle, characteristics of input current and output voltage of the proposed rectifier are analyzed in detail. Secondly, combined with the permanent magnetic synchronous generation wind power system, efforts are done to illustrate the relationship between the automatic-transformer rectifier and the wind turbine, after which the design details of automatic-transformer rectifier are obtained. The correctness of the theoretical analysis is validated using practical experiments performed by an experimental wind power system at last, and the results indicate the feasibility of using autotransformer rectifier in wind power applications.
