Cet article mene une etude detaillee du convertisseur Dual Active Bridge (DAB). Cette topologie de conversion DC/DC associe une source et une charge de nature capacitive au travers d’un element inductif, point-cle du dimensionnement. L’analyse d’une commande a decalage de phase permet d’etablir les contraintes sur les composants, en vue de leur dimensionnement. La presence de deux onduleurs en pont offre de nombreuses possibilites de commande qui seront etudiees pour ameliorer le rendement. Des extensions sont presentees comme le DAB a resonance serie dont le dimensionnement offre des particularites ou d’autres variantes pour la conversion directe AC/DC ou la connexion de trois reseaux DC.
