Predictive Control of Parallel Three-Phase Grid-tied Inverters: A Simple and Effective Solution to Mitigate Circulating Current

High power grid-tied inverters have attracted increasing attentions in energy conversion and electrical drives applications. Parallel configuration is a promising solution to enlarge the total power rating. However, zero-sequence loop arises in paralleled grid-tied inverters, hence introducing zero-sequence circulating current. This leads to the deceases of the effective power volume and additiona...
