Title (EN) HIGH FREQUENCY POWER CONVERTER BASED ON TRANSFORMERS
(FR) CONVERTISSEUR DE PUISSANCE HAUTE FRÉQUENCE BASÉ SUR DES TRANSFORMATEURS
Abstract: front page image
(EN)A transformer-based power conversion system includes a primary coil is provided in a current path that includes a single energy switch. An oscillator is coupled to a control input of the energy switch. The design conserves switch-based losses as compared to prior designs because a single switch is provided in a current path occupied by the primary coil. The design also provides improved conversion efficiency because parasitic capacitances associated with the energy switch cooperate with charge transfers generated by the oscillator.
(FR)L'invention porte sur un système de conversion de puissance basé sur des transformateurs qui comprend une bobine primaire dans un trajet de courant comportant un seul commutateur d'énergie. Un oscillateur est couplé à une entrée de commande du commutateur d'énergie. La conception réduit les pertes de commutation par comparaison aux conceptions antérieures car un seul commutateur est installé dans un trajet de courant occupé par la bobine primaire. La conception offre également un rendement de conversion amélioré étant donné que des capacités parasites associées au commutateur d'énergie coopèrent avec des transferts de charge générés par l'oscillateur.
