Dynamic Analysis and Control Design of a Step-Down Switched-Capapcitor Dc-Dc Converter

강압형 스위치드-커패시터 DC-DC 컨버터의 동특성해석 및 제어회로 설계

In this paper dynamic analyses and control design of a step-down switched-capacitor dc-dc converter are presented. Open-loop dynamics of the converter are analyzed using the stage-space averaging technique. A systmatic control design method that offers excellent closed-loop performance for the converter is proposed, The analysis results and dynamic performance of the converter are verified using 18 W experimental converter that delivers a 5V/3.5V output from a 11-16V input source.
