A Switched-Capacitor AC-AC Converter for 220V/55V and 55V/220V Applications

Abstract:

A novel type AC-AC converter based on the switched-capacitor principle is presented. The circuit topology of the switched-capacitor converter, the principle of operation, the equivalent circuit model and an example are described in this paper. In order to demonstrate the performance of this converter in the laboratory, this paper designs a prototype of 600W, 220V high-side voltage, 55V low-side voltage and switching frequency of 50 kHz. The experimental results verify the validity of the theoretical analysis.
