摘要
本文首先从简述级联型高压变频器系统拓扑结构入手,进而分析中性点偏移技术的原理及方法,在此基础上通过Matlab对有无中性点偏移功能两种情况的输出结果进行仿真,分析对比对两种情况下的仿真结果数据,验证算法的正确性。
In this paper, first introduces the System topology of Cascade high voltage in- verter, and analyzes the principle and method of neutral point shift, then through Matlab simulate the results of whether the neutral shift the output of two cases, analysis and com- parison of simulation results in both cases the data, verify the correctness of the algorithm.
