Abstract
An inductive power transmitter for inductive power transmission to an inductive power receiver is provided, comprising a primary coil, capable of being inductively coupled to a secondary coil in the inductive power receiver, a power supply and an associate driver configured to provide a varying electrical potential from the power supply to the primary coil, a monitoring system configured to measure electrical flow parameters of the primary coil, and a controller configured to detect, based on the electrical flow parameters measured by the monitoring system, an error condition indicative of a foreign object introduced between the primary coil and the secondary coil, and to facilitate, when the error condition is detected, interrupting the electrical potential to the primary coil.
