Technological inductive power transfer systems

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 K e y w o r d s: inductive power transfer, technological IPT, magnetic coupling, magnetic field lines, matching

Determination and Analysis of Joule’s Heat and Temperature in an Electrically Conductive Plate Element Subject to Short-Term Induction Heating by a Non-Stationary Electromagnetic Field

“…Induction heating of electrically conductive elements is performed using induced currents (Figure 1) by means of induction heating stations [23]. The action of induced currents at short-term induction heating by NEMF in MIMS is mathematically described by values of the component H y (z, t) on the surfaces z = ±h of the plate element, that can be written by the functions H ± y (t) in the form ( 14):…”
