AB Power converters are the basic elements of any power electronics system in many areas andapplications. Among them, the push–pull converter topology is one of the most widespread due to itshigh efficiency, versatility, galvanic isolation, reduced number of switching devices and the possibilityof implementing high conversion ratios with respect to non-isolated topologies. Optimal design andcontrol requires very accurate models that consider all the non-idealities associated with the actualconverter. However, this leads to the use of high-order models, which are impractical for the designof model-based controllers in real-time applications. To obtain a trade-off model that combines thecriteria of simplicity and accuracy, it is appropriate to assess whether it is necessary to consider allnon-idealities to accurately model the dynamic response of the converter. For this purpose, this paperproposes a methodology based on a sensitivity analysis that allows quantifying the impact of eachnon-ideality on the converter behaviour response as a function of the converter topology, power andfrequency. As a result of the study, practical models that combine the trade-off between precision andsimplicity are obtained. The behaviour of the simplified models for each topology was evaluatedand validated by simulation against the most complete and accurate non-ideal model found in theliterature. The results have been excellent, with an error rate of less than 5% in all cases
