摘要
针对传统的矩阵变换器(CMC)换流方法、调制算法比较复杂等问题,介绍了一种稀疏矩阵变换器SMC(sparse matrix converter)。首先给出稀疏矩阵变换器的拓扑结构;然后对稀疏矩阵变换器的换流、调制策略进行了详细分析;最后,利用Matlab软件对稀疏矩阵变换器进行建模仿真。仿真结果表明稀疏矩阵变换器拓扑结构正确、可行;调制、换流策略相对简单有效。
In order to reduce the complexity of converter and modulation scheme of CMC, a SMC is proposed in the paper. The author has presented several topologies of sparse matrix converter firstly. Then, analyzed the converter and modulation scheme. Finally, set up the simulation model of the sparse matrix converter by means of Matlab. Simulation results verified the validity of the topology and verified the effectiveness and feasibility of the converter and modulation scheme.
