Abstract

The invention provides a multi-purpose wireless charger. The charger includes a power amplifier module and electromagnetic emission systems; the power amplifier module includes a power amplifier integrated circuit; the power amplifier integrated circuit includes multiple high frequency alternating current generating circuits; the multiple high frequency alternating current generating circuits areused for generating multiple high frequency alternating current with different phases; the power amplifier integrated circuit is connected to the multiple electromagnetic emission systems and loads the high frequency alternating current of one phase on each electromagnetic emission system; and the electromagnetic emission systems are used for emitting the electric energy of the high frequency alternating current through electromagnetic coupling resonance. The charger can simultaneously and wirelessly supply power for multiple different loads, so that time can be saved, efficiency can be enhanced, and costs can be saved as well.

Description

technical field [0001] The present invention relates to a charger, in particular to a multi-purpose wireless charger. Background technique [0002] With the increasing use of mobile electronic devices such as mobile phones, the problem of charging has become a problem that must be faced when using electronic devices, especially when charging multiple devices at the same time, there will often be a problem of insufficient charging ports. [0003] At present, the charging devices on the market are mainly wired charging. In recent years, due to the development of wireless charging technology, some wireless charging devices have gradually appeared on the market. However, the wireless charging devices currently on the market are only suitable for specific loads and have a narrow range of use. [0004] In recent years, with the continuous development of magnetically coupled resonant wireless power transmission, the technology has become more and more mature, and the use of this t...
