In this article, three impedance networks based on three-winding switched-coupled-inductors (SCLs) are proposed that are improved compared to the successfully modified series and tapped SCL quasi-Z-source networks (mS/TSCL-qZSN). The proposed networks have three coupled windings in their topologies with their two turn ratios to be chosen arbitrarily, instead of only one turn ratio compared to the mS/TSCL-qZSNs. Consequently, a high degree of design flexibility is achieved that is accompanied by low peaks of both magnetizing and input currents, which let smaller magnetic elements including both the total required coupled inductances and the input inductance. Also, with the new configuration of the proposed circuits, the components' stresses, such as the total capacitors' voltages and the total switching device power ratings, are remarkably reduced compared to the origins. The performance principles and design criteria are explained in the article. Then, the investigative experimental results on a dc–dc laboratory prototype are presented. [ABSTRACT FROM AUTHOR]
