Description
La présente invention concerne un dispositif d’interface disposé entre une source de tension alternative tel que le réseau électrique domestique, et un appareil à alimenter sans fil sous une tension d’alimentation courante, notamment une tension alternative standard de 100 à 250 Volts et à une fréquence de 50 à 60 Hz.The present invention relates to an interface device arranged between an alternating voltage source such as the domestic electrical network, and a device to be powered wirelessly under a common supply voltage, in particular a standard alternating voltage of 100 to 250 Volts and at a frequency of 50 to 60 Hz.
ETAT DE LA TECHNIQUESTATE OF THE ART
On connait déjà plusieurs dispositifs permettant d’alimenter un équipement ou un appareil électrique au standard d’alimentation du réseau électrique domestique par l’intermédiaire d’une transmission d’énergie électrique sans contact filaire entre le réseau électrique (encore appelé « secteur ») et l’appareil à alimenter. Cette transmission d’énergie électrique se fait à l’aide d’une bobine primaire connectée au réseau électrique par l’intermédiaire d’un premier ensemble de circuits électroniques (encore appelé convertisseur amont), et cette bobine primaire est couplée électro magnétiquement à une bobine secondaire qui est elle-même connectée à l’appareil à alimenter par l’intermédiaire d’un second ensemble de circuits électroniques (encore appelé convertisseur aval).Several devices are already known which make it possible to supply electrical equipment or apparatus to the standard supply of the domestic electrical network by means of a transmission of electrical energy without wired contact between the electrical network (also called "mains") and the device to be powered. This transmission of electrical energy is done using a primary coil connected to the electrical network via a first set of electronic circuits (also called upstream converter), and this primary coil is electromagnetically coupled to a secondary coil which is itself connected to the device to be powered via a second set of electronic circuits (also called downstream converter).
Mais les solutions électroniques traditionnelles issues de l’état de l’art pour réaliser les deux ensembles de circuits électroniques sont complexes et onéreuses, tant au niveau du convertisseur amont (entre le réseau domestique et la bobine primaire) que du convertisseur aval (entre la bobine secondaire et l’équipement à alimenter). De ce fait elles ne sont pas bien adaptées pour la réalisation d’un dispositif d’interface pour la transmission sans fil d’énergie électrique entre le réseau d’alimentation électrique et un appareil domestique à alimenter.But the traditional electronic solutions resulting from the state of the art to produce the two sets of electronic circuits are complex and expensive, both at the level of the upstream converter (between the domestic network and the primary coil) and of the downstream converter (between the secondary coil and the equipment to be powered). As a result, they are not well suited for the production of an interface device for the wireless transmission of electrical energy between the electrical power supply network and a domestic appliance to be powered.
En outre, du fait de leur complexité et du nombre d’étages électroniques impliqués dans les convertisseurs amont et aval, et chaque étage ayant son propre rendement inférieur à 1, le rendement énergétique global du dispositif d’alimentation sans fil connu s’en trouve dégradé.Furthermore, due to their complexity and the number of electronic stages involved in the upstream and downstream converters, and each stage having its own efficiency of less than 1, the overall energy efficiency of the known wireless power supply device is degraded.
BUTS DE L’INVENTIONAIMS OF THE INVENTION
Il existe un nombre croissant d’applications, notamment domotiques, dans lesquelles l’alimentation électrique d’un appareil pourrait se faire avantageusement sans fil entre un générateur alimenté par le réseau et l’appareil à alimenter.There are a growing number of applications, in particular home automation, in which the power supply of a device could advantageously be done wirelessly between a generator powered by the network and the device to be powered.
Un exemple d’une telle application est décrit notamment dans le document WO2020/065143 A1 de la même demanderesse, relatif à un système de gestion multifonction de bandes électriques chauffantes et d’appareils électriques domestiques.An example of such an application is described in particular in document WO2020/065143 A1 by the same applicant, relating to a multifunction management system for electrical heating strips and domestic electrical appliances.
L’un des buts de la présente invention est donc de remédier aux inconvénients précités et de proposer un dispositif d’interface d’alimentation sans fil qui soit plus simple et moins coûteux que les solutions connues, tout en présentant des performances au moins comparables, voire supérieures, notamment en ce qui concerne le rendement de transmission d’énergie de l’interface d’alimentation sans fil.One of the aims of the present invention is therefore to remedy the aforementioned drawbacks and to propose a wireless power supply interface device which is simpler and less expensive than the known solutions, while presenting at least comparable performance, even higher, in particular with regard to the power transmission efficiency of the wireless power supply interface.
Un autre but de l’invention est de proposer un dispositif d’interface capable de proposer en sortie, au choix et en fonction des besoins des appareils à alimenter, soit une tension d’alimentation sinusoïdale identique à celle fournie par le réseau électrique, soit une tension d’alimentation différente de celle du réseau d’alimentation, mais tout en restant compatible avec certains appareils en pratique.Another object of the invention is to provide an interface device capable of offering at the output, as desired and depending on the needs of the devices to be powered, either a sinusoidal power supply voltage identical to that provided by the electrical network, or a supply voltage different from that of the supply network, but while remaining compatible with certain devices in practice.
Un autre but de l’invention est de proposer un dispositif d’interface ayant un poids et un encombrement réduits et qui puisse facilement être adapté et utilisé pour l’alimentation électrique sans fil d’une grande variété d’appareils domestiques, tels que des lampes, des appareils ménagers ou équivalent, jusqu’à une puissance d’alimentation de l’ordre de 150 à 300 Watts.Another object of the invention is to provide an interface device having reduced weight and size and which can easily be adapted and used for the wireless power supply of a wide variety of domestic appliances, such as lamps, household appliances or equivalent, up to a supply power of the order of 150 to 300 Watts.
Un autre but de l’invention est de proposer un dispositif d’interface mobile aisé à déplacer et à coupler électro magnétiquement avec un support pourvu d’antennes primaires de manière à alimenter électriquement des appareils fixes ou mobiles, notamment dans le cadre d’un environnement domestique ou de bureau.Another object of the invention is to propose a mobile interface device that is easy to move and to couple electromagnetically with a support provided with primary antennas so as to electrically supply fixed or mobile devices, in particular within the framework of a home or office environment.
