Abstract

The invention discloses a large-area desktop wireless charger. The large-area desktop wireless charger comprises a master control chip, a plurality of wireless charging emission assemblies and wireless charging receiving assemblies, and is characterized in that the wireless charging emission assemblies comprise emission coils and polarized capacitors which are connected in parallel, the wireless charging receiving assemblies comprise receiving coils and polarized capacitors which are connected in parallel, the receiving coils are coupled to the emission coils, and the master control chip is connected with the wireless charging emission assemblies. The large-area desktop wireless charger has the following advantages: 1, the charger can be provided simultaneously for charging multiple devices in a wireless mode; 2, output currents are automatically adjusted, and the scheme is scientific; and 3, the electromagnetic conversion rate is 95%, the utilization rate of energy is substantially improved, and the energy is effectively saved.

Description

technical field [0001] The present application belongs to the field of wireless charging, and in particular relates to a large-area desktop wireless charger. Background technique [0002] The current wireless charging method is mainly the standard qi scheme. The data of the qi standard is 3.7V input, and the output of the receiving coil is 5V / 1A. The effective receiving distance of the magnetic induction principle is less than 1cm, and the misalignment effectively covers 80% of the transmitting and receiving area. , the electromagnetic conversion rate is 75%, the transmitting coil and the receiving coil are not interchangeable, the effective impedance of the transmitting coil is between 0.5 ohm and 1 ohm, and the effective impedance of the receiving coil is 1 ohm. The qi standard in each program only accepts a pair Only one coil can be used to charge one device, and the energy utilization rate is low. [0003] Therefore, how to develop a large-area desktop wireless charger ...
