A different DC / DC high boost converter for autonomous system application

High boost converters have become important in applications for energy generation, like renewable sources; due to its ability to have high gain levels. High efficiency, few components, and low voltage and current stress on switches are features desired in these kinds of converters. In this paper a different dc/dc converter to increase the input voltage is proposed; two pairs of coupled magnetically coils are charged in parallel and discharged in series with the source, this permits to offer a high gain with few components, but also at good efficiency. The steady-state analysis of the topology is shown. But also experimental results and simulation are presented to illustrate the behavior of the system for an output power of 200 W. The system efficiency is around 95% at hard switching.
