Abstract
In order to more comprehensively compare a series of DC-DC converters with similar topological structures and functions and achieve optimal selection, a comprehensive evaluation method for DC-DC converter topology based on hierarchical analysis-entropy method is proposed. By summarizing the common performance indicators of DC-DC converters, a hierarchical evaluation index system is constructed. The indicators in the index system are weighted by the hierarchical analysis method and the abstract value method, respectively, and the combined weight is obtained by adopting a strategy focusing on the hierarchical analysis method. The linear weighted synthesis method is further used to obtain the score of each DC-DC converter. Finally, taking 11 D2DC-DC converter topologies with the same voltage gain as an example, the proposed method is used for comprehensive evaluation, and the feasibility of the evaluation results is analyzed.
