Abstract
This study presents a new boost converter based on Sheppard-Taylor topology for low-power applications. The proposed converter is capable of regulating output voltage under wide range of input voltage or load variations. Compared with the Sheppard-Taylor converter, the converter can be implemented with fewer components. The main switches of converter are turned on with zero-current-switching, and the rectifier diodes are turned off with zero-voltage-switching. A small-signal average model for the proposed converter is derived and transfer functions for the system output voltages are derived. The guidelines for the system design are provided. Finally, experimental results are given to confirm the system performance.
