| Popis: | In this article, a novel nonisolated buck–boost dc–dc converter is introduced with a wide range of conversion ratios. The proposed buck–boost converter, unlike the traditional one, draws continuous current from its input port. Moreover, the proposed converter has high step-up voltage gain, which makes it suitable for industrial and renewable energy applications. Operation principles and small-signal modeling of the proposed converter are addressed in detail. Furthermore, the proposed converter is compared with other buck–boost topologies regarding different criteria, such as the number of elements, voltage gain, switch stress, and the type of input current (continuous or discontinuous). By considering the features of the proposed converter, it can be used in renewable applications, specifically in photovoltaic systems. A prototype is developed to experimentally evaluate the validation of theoretical analysis. |
