WIRELESS CHARGER SYSTEM AND METHOD

摘要

A wireless charger system includes a charging module and at least one receiving module. The receiving module is configured to receive a power from the charging module wirelessly for charging a device. The charging module includes a source module, a control module, and a charging antenna. The receiving module includes a receiving antenna and a converting module. The control module is also configured to detect a perturbation of a current of the charging module. When the perturbation is detected, the control module is configured to increase a voltage outputted from the source module; when the perturbation is not detected, the control module is configured to decrease the voltage outputted from the source module. The disclosure further provides a wireless charger method.

1. A wireless charger system comprising:
a charging module comprising:
a source module configured to output a first direct current (DC) power;a control module coupled to the source module and configured to convert the first DC power to an alternating current (AC) power; anda charging antenna coupled to the control module; and at least one receiving module comprising:
a receiving antenna coupled to the charging antenna and configured to wirelessly receive the AC power from the charging antenna; anda converting module configured to convert the AC power received by the receiving antenna to a second DC power for charging a device; wherein the control module is also configured to detect a perturbation of the current level of the AC power, and the control module is further configured such that in event a such a perturbation is detected, the control module increases a voltage outputted from the first DC power, and further configured such that in event such a perturbation is not detected, the control module decreases the voltage outputted from the first DC power.
