Abstract Inductive power transfer is a very fast expanding technology with multiple design principles and practical implementations ranging from charging phones and computers to bionic systems, car chargers and continuous power transfer in technological lines. Only a group of devices working in near magnetic field is considered. This article is devoted to overview of different inductive power transfer (IPT) devices. The review of literature in this area showed that industrial IPT are not much discussed and examined. The authors have experience in design and implementation of several types of IPTs belonging to wireless automotive chargers and to industrial application group. Main attention in the article is paid to principles and design of technological IPTs

Recently, safety concerns related to electro-magnetic fields (EMFs) in inductive power transfer (IPT) systems for electric vehicles applications are pointed out. Magnetic flux concentrators are commonly used in the system to direct magnetic field lines and enhance the power transfer capability and efficiency. This article explores the performance of an IPT system for two different shapes of magnetic flux concentrators in terms of magnetic field distribution and power transmission efficiency. The dish-shape and plate-shape flux concentrators are examined and compared with a coreless IPT system. A simulation study based on three-dimensional finite-element analysis is carried out to design the magnetic couplers and analyze the IPT system’s performance. The simulation results are verified analytically and good matches are achieved.
