Özet
In this paper, we propose a simple direct AC-AC converter with cascade
connection by using switched-capacitor (SC) techniques. The proposed AC-AC converter
is synthesized with n (= 1, 2, . . ., N) converter blocks, where each converter block realizing
1/2× step-down conversion consists of only two capacitors and four switches. Unlike conventional SC converters, power conversion of the proposed converter is achieved without
a flying capacitor. Hence, the proposed converter can reduce circuit size from the conventional converters. Furthermore, high conversion ratio is realized by connecting these
converter blocks in series. In other words, multiple conversion is performed by cascade
topology. To evaluate the effectiveness of the proposed converter, we conducted simulation
program with integrated circuit emphasis (SPICE) simulations and theoretical analysis
concerning power efficiency and input power factor. The evaluation demonstrated that
the proposed converter can achieve better performance than the conventional converter
using a flying capacitor
