Title (EN) ELECTRIC POWER SUPPLY APPARATUS, CONTACTLESS ELECTRICITY TRANSMISSION APPARATUS, VEHICLE, AND CONTACTLESS ELECTRIC POWER TRANSFER SYSTEM
(FR) APPAREIL D'ALIMENTATION ÉLECTRIQUE, APPAREIL DE TRANSMISSION D'ÉLECTRICITÉ SANS CONTACT, VÉHICULE ET SYSTÈME DE TRANSFERT DE COURANT ÉLECTRIQUE SANS CONTACT
Abstract:
(EN) An electric power supply apparatus (20) includes a choke coil (210), a switching element (220), a resonance circuit (250) and a compensation circuit (260). The parasitic capacitance (270) of the switching element (220) is larger than a predetermined capacitance needed for realizing class E zero-voltage switching. The compensation circuit (260) is connected in parallel with the switching element (220). The compensation circuit (260) includes a coil (262) and a capacitor (264), and has inductive impedance.
(FR) L'invention concerne un appareil d'alimentation électrique (20) qui comprend une bobine d'arrêt (210), un élément de commutation (220), un circuit résonant (250) et un circuit de compensation (260). La capacité parasite (270) de l'élément de commutation (220) est supérieure à une capacité prédéterminée nécessaire pour effectuer une commutation à tension nulle de classe E. Le circuit de compensation (260) est monté en parallèle à l'élément de commutation (220). Le circuit de compensation (260) comprend une bobine (262) et un condensateur (264), et possède une impédance inductive.
