In this paper, a novel direct AC-AC converter based on the coupled inductor Z-source networks is proposed that offers a wide range of buck-boost operation. Two Z-source networks, called the coupled switched inductor (CSL) and the modified switched...

In this paper, a single-phase multilevel AC/AC converter with reduced number of power semiconductor devices is proposed. For the simple case of a three level converter, only three bidirectional switches and two capacitors are required. The proposed...
