级联型逆变器中基于混沌映射的均衡控制

Balance Control based on Chaos Mapping of Cascaded Inverter

当级联型逆变器级联单元较多时,存在各单元利用率不平衡问题。由于混沌映射具有随机性和确定分配的特点,可用于级联型逆变器。分析了循环分配的缺点,阐述了混沌映射分配的实现,给出了仿真和实验结果。

When number of cascaded unit increases,unbalance usage become a problem.There are random and equality distribution of chaos mapping.This paper analyzes demerit of rotate and swap method.The method of chaos mapping applied to cascaded inverter is proposed.Simulation and experiment results are given.
