Title (EN) INDUCTIVE POWER TRANSFER SYSTEM
(FR) SYSTÈME DE TRANSFERT DE PUISSANCE INDUCTIVE
Abstract:
(EN) An inductive power transfer system (1) for coupling a power source to a load across an air gap (11) is disclosed. The system (1) comprises a primary unit (3) associated with a host platform and a secondary unit (5) arranged to receive power transmitted inductively from the primary unit (3). The primary unit (3) includes a phase detection circuit (21) configured to detect phase changes in a signal in the primary unit (3) indicative of changes in an operating condition within the secondary unit (5), and a drive circuit (17). The drive circuit (17) is configured to adjust the power level transmitted to the secondary unit (5) depending on the detected phase.
(FR) La présente invention concerne un système de transfert de puissance inductive (1) destiné à coupler une source d'alimentation à une charge à travers un entrefer (11). Le système (1) comprend une unité primaire (3) associée à une plate-forme hôte et une unité secondaire (5) conçue pour recevoir la puissance transmise par induction à partir de l'unité primaire (3). L'unité primaire (3) comprend un circuit de détection de phase (21) conçu pour détecter des variations de phase dans un signal dans l'unité primaire (3) indiquant des variations d'une condition de fonctionnement au sein de l'unité secondaire (5), et un circuit d'attaque (17). Le circuit d'attaque (17) est conçu pour ajuster le niveau de puissance transmise à l'unité secondaire (5) en fonction de la phase détectée.
