Abstract:
Methods and devices for achieving a desired output in a resonant charge transfer device are given. In an exemplary embodiment a controlled resonant charge transfer device comprises first and second filter sections, first and second switch sections, a charge storage device, and a feedback control system. A method for controlling this device is given, the method comprising specifying a desired output and a desired charge storage voltage ratio; turning on first switches at first switch times and second switches at second switch times; measuring an actual output of the device and one or more parameters of the resonant circuit; determining an actual charge storage voltage ratio; computing corrected first switch times and corrected second switch times; on a subsequent operation cycle of the resonant charge transfer device, turning on the first switches at the corrected first switch times and the second switches at the corrected second switch times.
