Abstract
An enhanced receiver for wireless power transmission is disclosed. The receiver may be able to convert RF waves into continuous, stable and suitable voltage or power that can be used for charging or powering an electronic device. The receiver may include an antenna array for extracting and rectifying power from RF waves or pockets of energy. An input boost converter in the receiver may step up and stabilize the rectified voltage, while charging a storage element in the receiver. An output boost converter in the receiver may step up the output voltage of the storage element to deliver continuous and suitable power or voltage to a load. A microcontroller in the receiver may perform power measurements at different nodes or sections to adjust the operation of the input and output boost converters so that load power requirements can be satisfied at all times.
