Title
(EN) POLYPHASE SWITCHING REGULATOR
(FR) RÉGULATEUR DE COMMUTATION POLYPHASÉ
Abstract
(EN)
A switching regulator is disclosed comprising a high-voltage port, a low-voltage port, n number of switching poles, a magnetic element, and a controller. In turn, each switching pole connects across the high-voltage port and may consist of either one switch and one diode or two switches and two diodes. In turn, the magnetic element comprises a ferro-core having n number of magnetic branches, each of which includes a winding. Each winding start connects to the phase node of a respective switching pole, while each winding finish connects, in common, to one side of the low-voltage port. An n+1 th magnetic branch establishes a defined common-mode inductance which, in combination with transformer action, limits current ripple. The transformer action serves to exchange ripple power between phases such that the need for inductance is greatly reduced.

L'invention concerne un régulateur de commutation comprenant un port haute tension, un port basse tension, n pôles de commutation, un élément magnétique et un dispositif de commande. Chaque pôle de commutation est à son tour connecté au port haute tension et peut être constitué soit d'un commutateur et d'une diode, soit de deux commutateurs et de deux diodes. L'élément magnétique comprend, quant à lui, un noyau ferromagnétique contenant n branches magnétiques, dont chacune comprend un enroulement. Chaque début d'enroulement est connecté au nœud de phase d'un pôle de commutation respectif, tandis que chaque terminaison d'enroulement est connectée, en commun, à un côté du port basse tension. Une n+1ième branche magnétique établit une inductance en mode commun définie qui, en combinaison avec l'action de transformateur, limite l'ondulation de courant. L'action de transformateur sert à échanger la puissance d'ondulation entre des phases de manière à fortement réduire le besoin d'inductance.
