Power Balance Control Scheme of Cascaded Multilevel Inverter with Five Switches for Each H-bridge Unit
摘要
Abstract
A power balance control scheme of cascaded multilevel inverter with five switches for each H-bridge unit is proposed in this paper to improve the voltage and power levels of the inverter. Phase disposition modulation and phase-shift modulation are adopted,which has advantages of both good harmonic characteristics owing to phase disposition modulation and power balance distribution for each H-bridge unit owing to phase-shift modulation. The proposed scheme can not only output five levels that have good harmonic characteristics,but also achieve the output power bal-ance in one output cycle for each cell. A cascaded inverter consisting of three cells is taken as an example in the simula-tion,and the result verifies the validity and superiority of the proposed topological structure and its control scheme.关键词
