Switched Capacitor Based Two Switch Boost Converter for High Gain Applications

Abstract

A family of "Two-switch Boosting Switched capacitor Converters (TBSC)" is introduced, which distinguishes itself from the prior arts by symmetrically interleaved operation, reduced output ripple, low yet even voltage stress on components, and systematic expandability. Along with the topologies, a modeling method is formulated, which provokes the converter regulation method through duty cycle and frequency adjustment. In addition, the paper

also provides guidance for circuit components and parameter selection. A1KW 3X TBSC was built to demonstrate the converter feasibility, regulation capability via duty cycle and frequency, which achieved a peak efficiency of 97.5% at the rated power.
