摘要：For cascaded H-bridge inverter, phase disposition (PD) modulation strategy fails to achieve power balance among cascaded cells, although the output line voltage has optimal harmonic performance. In order to solve this problem, two kinds of power balance control methods using carrier rotation technique based on PD modulation strategy were proposed. Through carrier periodic rotation, the proposed methods could effectively realize the power balance control among the cascaded cells and retain the same harmonic characteristics of the output voltage under the PD modulation strategy. Three-cell cascaded H-bridge inverter was taken as an example. Firstly, the output power characteristics of the cascaded cells were deduced under the modified PD modulation strategy. Secondly, the mechanism of the proposed methods was analyzed and their characteristics were compared. Hence, the advantages and the applications of the two power balance control methods were revealed. Finally, simulation and experimental results verified the proposed methods. © 2018, Electrical Technology Press Co. Ltd. All right reserved.
