Abstract

This paper presents a new non-isolated high step-up topology by connecting two buck-boost DC/DC converters in the interleaved form. The presented topology has two identical buck-boost converters connected in a parallel-input, series-output manner for boosting the output voltage. This new topology can serve as an alternative to the typically used transformer isolated converter topology. A low-frequency modeling technique MISSCO is used to model and analyse the converter and simulations results are shown.
