A new method of extracting information from a current waveform for the purpose of controlling a resonant converter is presented. The method comprises sampling 3 times in half a period or sampling at 3 different positions in a sequence on different periods for the purpose of extracting the fundamental component and triangular component. The information can for instance be used for the purpose predicting the inductance and load of a circuit to indicate alignment in a inductive charging system. |
