Abstract:
(EN) The present invention relates to an induction heating and wireless power transmitting apparatus having an improved circuit structure. An induction heating and wireless power transmitting apparatus according to an embodiment of the present invention comprises: a first working coil unit comprising a first working coil and a second working coil 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; an auxiliary power source for supplying power to the first and second semiconductor switches; and a control unit for respectively controlling the operations of the first and second semiconductor switches and the first inverter unit.
(FR) La présente invention concerne un appareil de chauffage par induction et de transmission d'énergie sans fil comprenant une structure de circuit améliorée. Un appareil de chauffage par induction et de transmission d'énergie sans fil selon un mode de réalisation de la présente invention comprend : une première unité de bobine de travail comprenant une première bobine de travail et une seconde bobine de travail qui sont connectées en parallèle ; une première unité d'onduleur permettant d'appliquer un courant de résonance à la première bobine de travail et/ou à la seconde bobine de travail au moyen d'une opération de commutation ; un premier commutateur à semi-conducteurs connecté à la première bobine de travail de manière à activer/désactiver la première bobine de travail ; un second commutateur à semi-conducteurs connecté à la seconde bobine de travail de manière à activer/désactiver la seconde bobine de travail ; une source d'énergie auxiliaire permettant de fournir de l'énergie aux premier et second commutateurs à semi-conducteurs ; et une unité de commande permettant de commander respectivement les opérations des premier et second commutateurs à semi-conducteurs et de la première unité d'onduleur.
