An adaptable interleaved DC-DC boost converter

A new topology for an interleaved boost converter is presented in this paper. The circuit is able to provide high voltage gain without the need for using a large duty cycle. Analysis showing the effect of increasing inductor winding loss in relation to duty cycle is also presented. Losses in various components are considered and analysed. Finally, experimental results from a 200W prototype which was used to boost 25V to 300V are presented and verified the design.
