Title
(EN) HYBRID INDUCTIVE POWER TRANSFER SYSTEM
(FR) SYSTÈME DE TRANSFERT DE PUISSANCE INDUCTIF HYBRIDE
Abstract
(EN)
An inductive power transfer system (1) primary (20) or secondary circuit (21) has a first compensation network (6, 12) and second compensation network (7, 13). The compensation networks each have a different power transfer characteristic with respect to relative movement of the primary or secondary magnetic flux coupling structures (8, 9). The power transfer characteristics are such that one compensates for the other to allow a smooth or constant overall power transfer is despite the relative movement.
(FR)
Selon l’invention, un circuit primaire (20) ou secondaire (21) de système de transfert de puissance inductif (1) comporte un premier réseau de compensation (6, 12) et un deuxième réseau de compensation (7, 13). Les réseaux de compensation présentent chacun une caractéristique de transfert de puissance différente par rapport au mouvement relatif des structures de couplage (8, 9) de flux magnétique primaire ou secondaire. Les caractéristiques de transfert de puissance sont telles que l’une compense l’autre pour permettre un transfert de puissance global lisse ou constant en dépit du mouvement relatif.
