| Abstract: | The dq model of matrix converter based on doubly-fed wind generator is established, and a fluxoriented modulation scheme of the matrix converter is proposed in this paper. By this strategy, the duty cycle Of every switch is easy to be calculated for clear physical means, and the input power factor is flexible. An important conclusion about the zero component transmission manners in Matrix converters is drawn. The active and reactive power can be controlled respectively and harmonic can be suppressed by this method. The modulation scheme is used in a four poles doubly fed wind generator. The validity of the flux-oriented modulation scheme is verified. |
