Patent ID: 11233425

Abstract:
Embodiments of wireless power receivers are disclosed herein. For example, a wireless power receiver comprises an antenna configured to: receive radio frequency (RF) waves from a transmitter; and convert energy from the RF waves into alternating current. The wireless power receiver also includes a rectifier coupled to the at least one antenna that rectifies the alternating current into a direct current; and a charger, coupled to the rectifier, the charger configured to: receive the direct current; and control, via circuitry that is coupled with the charger, distribution of current using conduction paths: (i) to a load, and (ii) to and from at least one storage element coupled with the charger. In some embodiments, the circuitry is configured to select the one of the conduction paths based on: a respective power requirement of the load, a respective power requirement of the at least one storage element, and the direct current.
