Abstract

This paper introduces a zero-current-switching multilevel switched capacitor dc-dc converter for use in high voltage gain and high temperature applications. This circuit has a reduced charge path, low switch count and low device ratings compared to many similar topologies. Furthermore, switching losses and component size are greatly reduced. Zero-current-switching is achieved using small inductances in the circuit to resonate in series with the capacitors. In this way, the current is made to go to zero at the beginning and end of each switching cycle. A simulation is used to then verify the proposed converter.
