Abstract

This paper presents a new magnetic design for an Inductive (contactless) Power Transfer system (IPT) suitable for Automatic Guided Vehicle (AGV) applications. A new receiver is introduced in this paper, called a Bipolar Pad (BPP) pickup. This IPT system is designed to operate at a frequency of 10 kHz and is intended for use in material handling industrial applications. 3D Finite Element Method (FEM) software is used to analyse and design this system to transfer up to 300W across an air gap of 30 mm. A tolerance of 150 mm to lateral displacement on either side of the centre of a single phase track, which uses four conductors, is possible.
