Patent number: 9785159Abstract: A resonant power transfer system includes resonant circuitry (26) including an inductor coil (59) and a resonant capacitor (51) coupled to a first terminal (27) of the inductor coil, wherein the inductor coil and the resonant capacitor resonate to produce an excitation signal (IS) and a state variable signal (VCS1). Sub-sampling circuitry (30) samples first and second points of the state variable signal at a rate which is substantially less than the RF frequency of the state variable signal. Information recovery circuitry (32) produces a state variable parameter signal representing a parameter (A) of the state variable signal from information in the first and second sampled points. Control circuitry (38) produces a first control signal in response to the state variable parameter signal. Detection and optimization circuitry (41) produces a second control signal in response to the state variable parameter signal.Type: GrantFiled: April 8, 2014Date of Patent: October 10, 2017Assignee: Texas Instruments IncorporatedInventors: Gianpaolo Lisi, Gerard Socci, Ali Djabbari, Rajaram Subramonian, Kosha Mahmodieh
