Project #21: Ferrite-less pad for EV Charging

Back

Description:

Ferrite-less pads have now been proposed for the transmitting (on ground) pad of an IPT system for EV charging and other applications. They have the advantages of ruggedness as there is no fragile ferrite however they use more copper in the winding(s) and as a result they may have a cost and an efficiency penalty. The pads have a reflection winging that is very effective at reducing the flux under the ground but it does this by a flux cancellation process which is where the efficiency loss arises. This project is to examine the cost/efficiency penalty and see if it can be reduced. There has never been a suggestion that the ferrite-less pads could be used on the vehicle however no measurements of this have ever been done and the project will also look at this application and see if the pads can be used there and indeed if it is possible to have a system that is ferrite-less to ferrite-less and how the disadvantages can be mitigated. Finally reversible IPT systems are feasible but one has yet to be made with a ferrite-less pad and there may be improvements possible here.
