Abstract

Synchronous rectifier circuit topologies for a wireless power receiver receiving a supply of power from a wireless transmitter are disclosed. The synchronous rectifier circuit topologies include a half-bridge diode-FET transistor rectifier for rectifying the wireless power into power including a DC waveform, using a control scheme that may be provided by a delay-locked loop clock, or phase shifters, or wavelength links to control conduction of FET transistors in the synchronous rectifier circuit topology, and maintaining a constant switching frequency to have the diodes, coupled to FET transistors, to allow current to flow through each one respectively at the appropriate timing, focusing on high conduction times. The synchronous rectifier circuit topologies may enable power transfer of high-frequency signals at enhanced efficiency due to significant reduction of forward voltage drop and lossless switching.
