Recent Developments in Capacitive Power Transfer
Wireless power transfer technology offers significant improvement in convenience and electric safety for electric vehicle charging. In this presentation, we will review the recent developments in high power capacitive power transfer (CPT). It has been an established myth that good efficiency and stability of control was only possible at low power levels (in the tens of watts) and with low transfer distances in the millimeter range for CPT. We have shown that it is possible to achieve excellent efficiencies at the power level and distance applicable to EV charging, breaking the established myth, enabling a paradigm change on EV charging, and making low-cost wireless power transfer from science fiction to reality. CPT is now also combined with IPT to achieve higher power, better efficiency, and lower cost. Capacitive repeaters can increase the distance of CPT systems. Dynamic CPT will significantly reduce the cost and increase efficiency compared to IPT systems.
