用于道路无线电能传输的鲁棒性无铁氧体Double D拓扑

Roadway inductive power transfer depends on robust and reliable primary magnetic couplers (pads), but existing pads use large quantities of ferrite, a brittle magnetic material. This paper presents a ferrite-less variation on the Double D topology, removing the ferrite thereby making the system more mechanically robust, and then adding an additional reflection winding to help shape the field.
