Three-phase to three-phase AC/AC De-link converters based on three-level and two-level legs

摘要

This paper presents five topologies of back-to-back power converters based on a combination of two-level and three-level legs. Moreover, the proposed configurations share a leg between the grid side and load side converters. Analysis of THD and power switches losses are also addressed. Experimental and simulated results show the systems feasibility.
