Abstract
A multi-mode multi-coupling multi-protocol wireless power transmitter (WPT) and its embodiments transmit power to a wireless power receiver (WPR) in a power transfer mode (PTM) and a wireless power protocol (WPP) of the WPR. A first circuit of the WPT includes inductors or capacitors emanating power via a magnetic field or electric field PTM respectively. The WPT sequentially parses a test condition to identify a PTM, a power coupling linkage (PCL) between the WPT and the WPR, and a WPP of the WPR. The WPT identifies a match if the PTM of the first circuit and the WPP of the switch network, the variable matching circuit, a modulator/demodulator block or an out-of-band communication block, and a control logic circuit of the WPT match the PTM and the WPP of the WPR to transmit power to the WPR based on the match.
