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) ...

determine and compare the CMV of the ZSUSMC with four well-known impedance networks, namely cascaded, switched-inductor, quasi and series, in its structure, and 2) propose modulation techniques for CMV reduction in the ZSUSMCs. To this end, first...
