A Novel Strategy to Maximize the modulation index Under Unbalanced DC Sources
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 1
Abstract
In this paper a new NVM (Neutral modulation method) technique has been proposed to achieve balanced output in the multilevel cascaded inverter (MLCI) operating under unbalanced DC conditions. In order to examine these effects, a neutral voltage modulation strategy is proposed to accomplish output voltage balancing as well as to broaden the linear modulation range up to the maximum reachable point. In the proposed method, too large of a dc-link imbalance prevent the balancing of the output voltages.
