In this paper, a new step-up/step-down AC-AC converter is designed by switched capacitor (SC) techniques. The main features of the proposed SC AC-AC converter are the symmetrical converter topology and the absence of magnetic elements. Owing to the symmetrical converter topology, the number of capacitors in the proposed AC-AC converter is fewer than that in the conventional SC AC-AC converter. Furthermore, the proposed AC-AC converter has a smaller SC resistance than the conventional SC AC-AC converter. Therefore, the proposed AC-AC converter can improve power efficiency and input power factor from the conventional SC AC-AC converters. The principle of operation, qualitative analysis, and simulation evaluation are described concerning the proposed AC-AC converter with three stages. The results of the simulation program with integrated circuit emphasis (SPICE) simulation demonstrate the feasibility and effectiveness of the proposed ACAC converter.
