Abstract
In mega watts´ grid connected inverter for wind turbine, challenge exists in module parallel for high power, low switching frequency and optimized design of output LCL filter. Concerning with these key issues, this paper adopts filter inductor to realize current sharing and phase shifting of carrier wave to increase equivalent switching frequency; correspondently, optimized design rule of the LCL filter is given in detail. All approaches and design rules come from a practical project implementation and based on deep principle analysis. These schemes are validated feasible for high power inverter by simulation results.
