摘要
矩阵变换器是一种直接能量转换装置,由于无中间贮能环节,输入侧的任何扰动将会降低输出特性和可靠性.针对SPWM矩阵变换器提出了反馈补偿和前馈补偿2种补偿方式.分析了基本补偿原理,并针对各种不同的输入条件(对称、不对称和突变),通过Matlab/Simulink建立仿真模型,对2种方案进行了仿真比较,验证了2种控制策略的正确性和有效性.
Matrix Converter （MC） is a direct energy conversion device with high input power factor and regeneration capability. As a device without dc link elements, the ac line side disturbances can degrade its output characteristic and reliability. In this paper, feedback compensation method and feedforward compensation method are developed respectively to compensate the output voltages of MC and ensure the performance of output voltage under abnormal input voltage conditions. The two Matlab simulation models are established for the matrix converters with two compensation methods. The effectiveness and feasibility of the proposed two compensation methods have been compared through numerical simulations.
