摘要
简要介绍矩阵变换器的基本原理和主要优点,提出了一种基于空间矢量调制矩阵变换器的闭环控制方法,为达到降低开关损耗和谐波分量的目的,对开关控制脉冲进行合理排序以减少开关次数,并结合闭环控制实现矩阵变换器系统控制。最后通过仿真波形验证了所述控制方法的正确性和有效性。
In this paper, the operation principle and primary merits of Matrix converter is depicted, a closed-loop control method for the matrix converter based on space vector modulation is also proposed. In order to reduce the switching loss and harmonic components, an optimized nine-segment modulation strategy is adopted here. The validities of the control method are verified by the simulation result.
