ADJUSTABLE DELAY TO CONTROL NODE MISMATCH

원문 (중국어)

A wireless power transmitter is disclosed that comprises a coil, a first node electrically connected to a first side of the coil, a second node electrically connected to a second side of the coil, a plurality of transistors that are configured to drive the coil via the first and second nodes between a first voltage potential and a second voltage potential and a monitor circuit that is configured to determine the timing at which a first voltage of the first node and a second voltage of the second node cross a halfway point between the first voltage potential and the second voltage potential. The wireless power transmitter further comprises a feedback circuit that is configured to adjust a delay corresponding to at least one transistor of the plurality of transistors based at least in part on the first and second times.
