Summary:This paper proposes a new magnetic charging design for Inductive Power Transfer systems (IPT) based on a flat solenoid. The proposed design uses a single transmitter pad to transfer energy to two receivers pads. This magnetic design is suitable for stationary charging system applications including automatic Guided Vehicles (AGVs) and public transportation electric vehicles like buses. A 3D Finite Element Method (FEM) software is used to optimize the magnetic design to achieve better coupling between the transmitter and the receiver. The interoperability of the proposed design with polarized and non-polarized pads is also addressed in this work. The compliance of magnetic coupler with the ICNIRP guidelines is investigated through simulation. An experimental prototype is built to validate the optimized pads with results that differ by 8% in the worst scenario.
