L'inspection minutieuse de l'efficacité d'un convertisseur DC-DC et de sa dépendance à différents paramètres est depuis longtemps une préoccupation majeure des spécialistes de l'électronique de puissance. Bien que des recherches approfondies aient été effectuées sur l'estimation séparée de la perte de puissance pour différents composants d'un convertisseur DC-DC, il n'existe aucune étude complète concernant l'analyse de la perte de puissance dans un convertisseur DC-DC. Dans cette recherche, une description détaillée et les considérations nécessaires pour analyser la perte de puissance de tous les composants d'un convertisseur DC-DC Push-Pull sont présentées. La topologie Push-Pull est le meilleur choix pour étudier les problèmes d'efficacité, car elle présente tous les différents types de perte de puissance habituellement rencontrés dans les convertisseurs DC-DC. Cette recherche propose et vérifie des modèles de perte de puissance appropriés pour tous les composants d'un convertisseur DC-DC qui dissipent de la puissance. À cette fin, des modèles de perte de conduction et de commutation de tous les composants concernés sont entièrement développés. Les équations associées sont implémentées dans l'environnement MATLAB pour simuler toutes les causes possibles de perte de puissance dans le convertisseur. Afin de fournir un banc d'essai pour l'évaluation des modèles de perte proposés et de l'efficacité du convertisseur, un convertisseur DC-DC Push-Pull de 50 W a été conçu et mis en œuvre. Les résultats expérimentaux sont entièrement conformes aux résultats de simulation dans différentes tensions d'entrée, conditions de charge et fréquences de commutation. Il a finalement été démontré que les modèles proposés estiment avec précision l'efficacité du convertisseur DC-DC.

Abstract: Careful inspection of efficiency in a DC-DC converter and its dependence on different parameters have been key concerns for power electronic specialists for a long time ago. Although extensive research has been done on the estimation of power loss for different components in a DC-DC converter separately, there isn't any comprehensive study regarding power loss analysis in a DC-DC converter. In this research, detailed description and necessary considerations in order to analyze the power loss of all components in a Push-Pull DC-DC converter are presented. Push-Pull topology is the best choice for investigating efficiency issues, since it exhibits all different types of power loss that are usually encountered in DC-DC converters. This research proposes and verifies appropriate power loss models for all components in a DC-DC converter that dissipate power. For this purpose, conduction and switching loss models of all the relevant components are fully developed. The related equations are implemented in MATLAB environment to simulate all possible causes of power loss in the converter. In order to provide a test bed for evaluation of the proposed loss models and the converter efficiency, a 50 W Push-Pull DC-DC converter was designed and implemented. The experimental results are in full accordance with the simulation results in different input voltages, load conditions and switching frequencies. It was finally shown that the proposed models accurately estimate the DC-DC converter's efficiency.
