Abstract:
(EN) The present invention relates to an induction heating and wireless power transmitting apparatus having an improved control algorithm. An induction heating and wireless power transmitting apparatus according to an embodiment of the present invention comprises: a first working coil unit comprising first and second working coils which are parallelly connected; a first inverter unit for applying a resonant current to the first working coil and/or the second working coil by means of performing switching operation; a first semiconductor switch connected to the first working coil so as to turn the first working coil on or off; a second semiconductor switch connected to the second working coil so as to turn the second working coil on or off; and a control unit for detecting whether an object is positioned on the first working coil or the second working coil, by means of respectively controlling the operations of the first and second semiconductor switches and the first inverter unit.
(FR) La présente invention concerne un appareil de transmission d'énergie sans fil et de chauffage par induction ayant un algorithme de commande amélioré. Un appareil de transmission d'énergie sans fil et de chauffage par induction selon un mode de réalisation de la présente invention comprend : une unité à bobines de service comprenant des première et deuxième bobines de service qui sont branchées en parallèle ; une première unité d'onduleur destinée à appliquer un courant résonant à la première bobine de service et/ou à la deuxième bobine de service en effectuant une opération de commutation ; un premier commutateur à semiconducteur relié à la première bobine de service de façon à la mettre sous tension ou hors tension ; un deuxième commutateur à semiconducteur relié à la deuxième bobine de service de façon à la mettre sous tension ou hors tension ; et une unité de commande destinée à détecter si un objet est positionné sur la première ou la deuxième bobine de service, en commandant respectivement le fonctionnement des premier et deuxième commutateurs à semiconducteur et de la première unité d'onduleur.
