Title
(EN) WIRELESS CHARGING CIRCUIT, CHARGING DEVICE, AND DEVICE TO BE CHARGED
(FR) CIRCUIT DE CHARGE SANS FIL, DISPOSITIF DE CHARGE ET DISPOSITIF À CHARGER
(ZH) 无线充电电路、充电设备以及待充电设备
Abstract
(EN) Provided are a wireless charging circuit, a charging device, and a device to be charged. The wireless charging circuit comprises a transmitter circuit (501), a rectifying circuit (502) and an inverter circuit (503), wherein an output end of the rectifying circuit (502) is connected to an input end of the inverter circuit (503), and an output end of the inverter circuit (503) is connected to the transmitter circuit (501); the transmitter circuit (501) comprises a first transmitting coil (501a) and a second transmitting coil (501b), with the first transmitting coil (501a) and the second transmitting coil (501b) being connected in series, and each of the first transmitting coil (501a) and the second transmitting coil (501b) comprising a cylindrical magnetic core and a wire wound onto the cylindrical magnetic core; and the charging device and the device to be charged are provided with the wireless charging circuit. Adaptation thereof to a narrow space or an irregular space can thus be achieved without reducing the charging performance.
(FR) Sont prévus un circuit de charge sans fil, un dispositif de charge et un dispositif à charger. Le circuit de charge sans fil comprend un circuit émetteur (501), un circuit redresseur (502) et un circuit onduleur (503), une extrémité de sortie du circuit redresseur (502) étant connectée à une extrémité d'entrée du circuit onduleur (503), et une extrémité de sortie du circuit onduleur (503) étant connectée au circuit émetteur (501) ; le circuit émetteur (501) comprend une première bobine de transmission (501a) et une seconde bobine de transmission (501b), la première bobine de transmission (501a) et la seconde bobine de transmission (501b) étant connectées en série, et chacune de la première bobine de transmission (501a) et de la seconde bobine de transmission (501b) comprenant un noyau magnétique cylindrique et un fil enroulé sur le noyau magnétique cylindrique ; et le dispositif de charge et le dispositif à charger sont dotés du circuit de charge sans fil. L'adaptation de ceux-ci à un espace étroit ou à un espace irrégulier peut ainsi être obtenue sans réduire les performances de charge.
(ZH) 提供了一种无线充电电路、充电设备以及待充电设备。无线充电电路包括:发射端电路(501)、整流电路(502)和逆变电路(503),整流电路(502)的输出端与逆变电路(503)的输入端连接,逆变电路(503)的输出端与发射端电路(501)连接;发射端电路(501)包括:第一发射线圈(501a)和第二发射线圈(501b),第一发射线圈(501a)和第二发射线圈(501b)串联连接,第一发射线圈(501a)和所述第二发射线圈(501b)均包括柱形磁芯和缠绕在所述柱形磁芯上的导线;充电设备与待充电设备具有该无线充电电路。可以在不降低充电性能的前提下,适应窄空间或不规则空间。
