Patent attributes
The present disclosure provides methods and systems for maximum power point transfer (MPPT) in receivers. An example system includes: a plurality of antenna elements configured to receive a wireless signal comprising energy; a plurality of rectifiers corresponding to the antenna elements and configured to rectify the energy; an input boost converter configured to step up the energy, wherein the input boost converter is further configured to determine at least one of a global power maximum and a local power maximum produced in the rectifiers; and a controller configured to determine an available energy at the rectifiers, wherein the controller is further configured to determine a maximum power point value from the rectifiers via the input boost converter, and wherein the controller is further configured to transmit an operational instruction to the input boost converter to further step up the energy rectified by the rectifiers.
