Abstract
A more efficient solution for a detection of operating conditions in an inductive power transfer system and for improved control of the inductive power transfer system. An operating condition at a secondary side of an inductive power transfer system is detected by measuring at least one electric variable at a primary side of the inductive power transfer system which is dynamically coupled to the operating condition at the secondary side of the inductive power transfer system. Then follows an analysis of the at least one electric variable over time at the primary side of the inductive power transfer system. This allows to detect a change of the operating condition at the secondary side of the inductive power transfer system. Also provided is a control method and related controller apparatus using the detection method.
