Abstract

The invention relates to a wireless charging device with an adjustable charging area and a method thereof. Based on an array antenna, a multi-coil transmitting and single-coil receiving model, by using a parallel magnetic coupling resonant principle and adjusting an input voltage of a unit in an transmitting coil array, changes the charging area. The wireless charging device is suitable for wireless charging in the fields of mobile phones, UAVs, and electric vehicles. Different from a traditional single-coil model, the wireless charging device has a long transmission distance, a good anti-offset capability and high transmission efficiency, is beneficial to the application in a wireless energy transmission system and greatly improves user experience.

Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a wireless charging device with an adjustable charging area and a method thereof. Background technique [0002] The discovery of electricity has greatly changed people's lives, and it can be said that we can never do without it. But since the use of electricity, wires have been with us all the time, and wires all over the space or table have brought us a lot of trouble. Whether we can make our surrounding environment more tidy and make our electrical equipment work normally without using wires has become our dream. Therefore, the wireless power transmission technology (Wireless Power Transmission, WPT) emerges at the historic moment under such a background. Wireless power transfer technology has very attractive prospects. For example, it can charge implanted devices in the human body outside the body, saving patients from the pain of replacing batteries through sur...
