Abstract
(EN)
The wireless power supply device 3 has a power-transmission coil L1 for wirelessly transmitting electric power to a power-reception coil L2. The wireless power supply device 3 is equipped with: a power-transmission resonance circuit including a power-transmission capacitor C1 and the power-transmission coil L1; a power-transmission core around which the power-transmission coil is wound; first switching components S11, S12 which are controlled to turn on/off on the basis of a first PWM signal P1 and second switching components S21, S22 which are controlled to turn on/off on the basis of a second PWM signal P2; and a control unit 4 for supplying the first PWM signal P1 and the second PWM signal P2. The control unit 4 changes the duty ratio of the first PWM signal P1 and that of the second PWM signal P2 in accordance with the relative position of the power-transmission coil L1 to the power-reception coil L2.

L'invention concerne un dispositif d'alimentation électrique sans fil (3) qui comporte une bobine d'émission d'énergie (L1) pour envoyer sans fil de l'énergie électrique à une bobine de réception d'énergie (L2). Le dispositif d'alimentation électrique sans fil (3) est équipé : d'un circuit résonnant d'émission d'énergie comprenant un condensateur d'émission d'énergie (C1) et la bobine d'émission d'énergie (L1); d'un noyau d'émission d'énergie autour duquel la bobine d'émission d'énergie est enroulée; de premiers composants de commutation (S11, S12) qui sont commandés pour être bloqués/débloqués sur la base d'un premier signal PWM (P1) et de seconds composants de commutation (S21, S22) qui sont commandés pour être bloqués/débloqués sur la base d'un second signal PWM (P2); et d'une unité de commande (4) pour fournir le premier signal PWM (P1) et le second signal PWM (P2). L'unité de commande modifie le rapport cyclique du premier signal PWM (P1) et celui du second signal PWM (P2) en fonction de la position relative de la bobine d'émission d'énergie (L1) par rapport à la bobine de réception d'énergie (L2).
