Title: MOVABLE THREE-DIMENSIONAL WIRELESS CHARGING DEVICE FOR MULTIPLE PHONES
Abstract:
Provided is a movable three-dimensional wireless charging device for multiple phones, comprising: a power input, a direct current power supply for inversion, a high-frequency inversion circuit, a primary compensation network, a loosely coupled transformer formed from a primary coil (a transmitting coil) and a secondary coil (a receiving coil), a secondary compensation network, and an output regulating circuit. The power input is connected to the direct current power supply for inversion; an output end of the direct current power supply for inversion is connected to the high-frequency inversion circuit; an output end of the high-frequency inversion circuit is connected to the primary compensation network, and then connected to the primary coil of the loosely coupled transformer; the secondary coil of the loosely coupled transformer is arranged in the primary coil, and an output end of the secondary coil is connected to the secondary compensation network, and then connected to the output regulating circuit, and an output end of the output regulating circuit is connected to a load. According to the invention, a uniform electromagnetic field can be provided in a three-dimensional space within a primary coil, and multiple mobile phones can be wirelessly charged at any position in the coil at the same time. The invention is especially suitable for charging mobile phones in a moving automobile.
