Integrated flyback topologies for high step-up voltage conversion

This paper presents a new methodology to generate high step-up voltage gain converters based on the combination of two standard DC/DC converters. The converters are combined so that their Input sections are integrated reducing the converter component count. Their Output sections are associated to derive three basic configurations, the series, the parallel and the cascade outputs. The paper presents as an example, the integration of the boost and flyback converters with experimental results.
