基于电容电压优化排序算法的M3C控制策略
M3C control strategy based on capacitor voltage optimization sorting algorithm
摘要
Abstract
Objectives In order to address issues including the high number of comparisons in the traditional sub-module capacitor voltage sorting algorithm and the significant switch losses due to repeated switching of the same sub-module with the same number of sub-modules,an optimized sorting algorithm was proposed.Methods This algorithm grouped the capacitor voltage values of the sub-modules and performed sorting only within each group,effectively avoiding unnecessary repetitive sorting.Furthermore,by setting the allowable range of capacitor voltage fluctuations,the switch frequency of the sub-modules was optimized.Results Simulation results demonstrated that the proposed optimization sorting algorithm effectively reduced the number of sorting times and shortened the sorting time without affecting the capacitor voltage balance.More-over,after switch frequency optimization,the switching frequency of the sub-module switches was signifi-cantly reduced.Conclusions Under the same conditions,the optimized sorting algorithm improved sorting efficiency without affecting the sub-module capacitor voltage and switch frequency.After the switch fre-quency optimization,unnecessary repetitive switching of the switches was effectively avoided when the sub-module capacitor voltage fluctuated slightly,reducing and the switching losses was reduced.关键词
