Optimizing Design of Dual-Input Buck DC/DC Converter

Abstract:

In hybrid renewable power systems, the use of a multiple-input dc/dc converter (MIC) leads to simpler circuit and lower cost, compared to the conventional use of several single-input converters. This paper focuses on the optimizing design of MIC. Different from a single–input DC/DC converter, the parameters design of a MIC is very complicated. This is because the converter will operate in multiple operation modes, in which the power sources can deliver power o the load either simultaneously or individually. In this paper, an optimizing design method is proposed with the considerations of the multiple operation modes. A dual-input Buck converter is taken as an example to show the design method and a prototype is built to verify the theoretical analysis.
