Abstract
One example device for overcurrent protection for wireless power receivers includes a wireless power antenna comprising a wire coil; a conditioning circuit electrically coupled to the wireless power antenna to receive an electric power signal from the wireless power antenna; a temperature-sensitive fuse electrically coupled between the wireless power antenna and the conditioning circuit and configured to electrically decouple the wireless power antenna from the conditioning circuit in response to being blown; and a thermal energy source configured to generate thermal energy based on an electrical signal from an output of the conditioning circuit, the thermal energy source positioned proximate the temperature-sensitive fuse.
