Abstract: A wireless charging system includes a wireless charging device and a power-consuming device installed in a charging area. The wireless charging device has a signal conversion module connected to a controller, a transmitter antenna and a power input terminal. The power-consuming device has a receiver coil connected to a rectifier and outputting generated power through a power output terminal. Before or when the wireless charging device charges the power-consuming device, the controller of the wireless charging device can detect a power consumption status, voltage and current information and phase difference information of the transmitter antenna to instantly determine if any foreign metal object enters the charging area, thereby preventing high temperature generated by the foreign metal object from causing equipment damage and danger and enhancing wireless charging safety.

Abstract: A control method for a wireless charging system has steps of performing impedance matching on an antenna of the wireless charging system; tracing an optimal frequency point by sending a sensing signal with a default transmission frequency, and calculating a transmission efficiency of the sensing signal; determining whether the transmission efficiency meets a transmission requirement. When the transmission efficiency does not meet the transmission requirement, repeats the previous steps with another default transmission frequency until the transmission efficiency meeting the transmission requirement. When the transmission efficiency meeting the transmission requirement, the default transmission frequency is defined as the optimal frequency point for charging.

Abstract: An antenna with a concentrated magnetic field has a main coil and at least one pair of auxiliary coils. Each of the main coil and each auxiliary coil has at least one coil conductor. Each one of the at least one coil conductor has a virtual reference plane. The at least one pair of auxiliary coils are mounted around the main coil and an included angle is formed between the virtual reference plane of each coil conductor of each auxiliary coil and that of each coil conductor of the main coil. Lines of magnetic field generated by each coil conductor of each auxiliary coil concentrate the lines of magnetic field of the main coil to orient to a corresponding virtual reference plane of the main coil, thereby solving the magnetic leakage and EMI easily occurring outside the zone of active transmission for conventional coils using electromagnetic induction.
