| Summary: | Abstract Inductive Power Transfer (IPT) system is an appealing approach among researchers as well as industrial manufacturers of electric vehicle (EV) charging systems. IPT can be used to transfer power through the air gap by generating a high‐frequency current in the transmitter pad and inducing current magnetically in the receiver pad. A triple quadrature pad (TQP) has been proposed to enhance transferred power in larger misalignments and various air gaps. This pad excels in its previous three‐coil structures by implementing a fewer number of inverters and lower dimensions compared to other similar structures. All these features result in a higher coupling coefficient in low misalignments and higher tolerance to misalignment in horizontal displacements. A laboratory‐scale prototype has been designed and built for 26 kHz switching frequency and 150 mm air gap in order to deliver maximum power in different displacements. Simulations have been done by the finite element analysis (FEA) tool of ANSYS Maxwell. The prototype has been built to validate the simulation results. |
