Switched capacitor four-quadrant DC/DC Luo-converter

Classical DC/DC converters usually consist of inductors and capacitors such as buck converter, boost converter, buck-boost converter, Luo-converters and Cuk-converter. All classical converter has big size and low power density. Switched-capacitors have been successfully employed in the inductorless DC/DC converters and opened the way to build the converters with high power density. However, most of these converters in the literature perform in single-quadrant operation. Some of them work in the push-pull status, and their control circuit and topologies are very complex. This paper introduces a switched capacitor four-quadrant DC/DC Luo-converter. The experimental results verified our analysis and calculation
