Description
Summary:This paper presents a practical prototype of a recent multiphase (quadrature) pick-up suited for contactless power transfer systems. The investigation is based on a commercial pick-up design for automatic guided vehicle systems and is evaluated in terms of its ability to extend the allowable tolerance of this pick-up receiver to the track while achieving the desired output power profile with good efficiency, without compromising normal operation. Practical aspects of the design are discussed along with means by which magnetic design and electronic compensation can be used to improve performance.
