Abstract

This disclosure provides systems, methods, and apparatus for filtering of a rectifier in a wireless power receiver. In one aspect a wireless power receiver is provided. The wireless power receiver includes a rectifier circuit configured to provide direct-current (DC) based at least in part on a time-varying voltage generated via a wireless field provided from a wireless power transmitter. The wireless power receiver further includes a band-stop filter circuit configured to filter an output of the rectifier circuit and electrically isolate a capacitor from the rectifier circuit at an operating frequency.
