【Abstract】 Various modulation schemes have been proposed for control of matrix converter, but most of them have the problems, such as complexity and computation. In order to settle them, a simple modulation scheme based on mathematical construction is proposed in this paper. The modulation does not need any sector information. It is simple to understand and easy to implement. Meanwhile, it can ensure maximum input power voltage transfer ratio of 0.866 and controllable input power factor. What matters most in using this method is it can be generalized in other similar schemes and optimized them as a result. The availability and correctness of the scheme are carefully verified by experiments.更多还原
