SYSTEMS AND METHODS FOR EXTENDING THE POWER CAPABILITY OF A WIRELESS CHARGER

摘要

Systems and methods for converting voltages between different voltage levels in a receiver are disclosed. In an aspect, a wireless power receiver apparatus for charging a chargeable device is provided. The wireless power receiver apparatus for charging a chargeable device can include a receive antenna configured to wirelessly receive power at a level sufficient for charging the chargeable device. The wireless power receiver apparatus can also include converter circuitry. The converter circuitry can be coupled to the receive antenna. The converter circuitry can be configured to receive an input voltage derived from the wirelessly received power. The converter circuitry can also be configured to produce an output voltage that is scaled to a value relative to the input voltage based on a relationship between the input voltage and a first voltage level threshold.
