Gain and Efficiency Analysis of 2-Stage Switched Capacitor (SC) Boost Based dc-dc Converter

摘要

This paper presents the theoretical analysis, operating principles, and comparison between basic boost and 2-stage switched capacitor (SC) based boost converter. Using volt-second balance and current charge principle, voltage gain and efficiency are theoretically derived for the basic boost and 2-stage SC based boost converter. MATLAB software has been utilized to simulate the predicted results. Simulation results, which are in complete agreement with the predicted results, have been analysed and compared with the results of the basic boost converter. Largely increased voltage gain with a commendable efficiency for the 2-stage SC based boost converter, validate the authenticity of the proposed system.
