| Opis: | This paper proposes an on-line method for foreign object detection in a double DD coil
system. The foreign object is detected by real-time measurement of the mutual inductance between
the transfer pads. Measurement of the mutual inductance between coils can be performed at the
start, during initialisation, or during the wireless power transfer. The coils in the double DD coil
structure can be used separately; one coil can be used for power transfer and the other can be used
for the mutual inductance measurement. The mutual inductance measurement is based on the
voltage measurement across the open circuit receiver coil. The measured value of mutual inductance
between the transmitter and the receiver pad can be used in a control algorithm and in a foreign
object detection algorithm. Additionally, a 2DDq coil structure can be used as a replacement for the
double DD coil structure, which increases the power transfer density. The DD coils in the double DD
coil structure can also be driven using two phase-shifted voltages, which enables better location and
detection of foreign objects. The method also helps to differentiate the mutual inductance change due
to the distance change from the mutual inductance change due to the presence of a foreign object. |
