Title (EN) A POWER CONVERTER AND POWER CONVERSION METHOD
(FR) CONVERTISSEUR DE PUISSANCE ET PROCÉDÉ DE CONVERSION DE PUISSANCE
Abstract:
(EN) A power converter uses a transformer with main first (primary) and second (secondary) windings and having a main output and at least one auxiliary output. A third winding is for connection to a first auxiliary power supply output, and there is also a fourth winding. A variable dummy load is connected to at least the fourth winding and is used regulate the first auxiliary power supply output. Controlling the variable dummy load to increase the load at the fourth winding in order to increase a power at the first auxiliary power supply output. There may be two variable loads, each associated with a different transformer winding so that they have different influences on the output delivered to the first auxiliary power supply output.
(FR) La présente invention concerne un convertisseur de puissance utilisant un transformateur avec des premier (primaire) et deuxième (secondaire) enroulements principaux et ayant une sortie principale et au moins une sortie auxiliaire. Un troisième enroulement est destiné à être connecté à une première sortie de puissance électrique auxiliaire, et il existe également un quatrième enroulement. Une charge fictive variable est connectée au moins au quatrième enroulement et est utilisée pour réguler la première sortie de puissance électrique auxiliaire. La commande de la charge fictive variable est réalisée pour augmenter la charge au niveau du quatrième enroulement afin d'augmenter une puissance au niveau de la première sortie de puissance électrique auxiliaire. Il peut y avoir deux charges variables, chacune associée à un enroulement de transformateur différent de sorte qu'elles ont des influences différentes sur la sortie délivrée à la première sortie de puissance électrique auxiliaire.
