Title:
POSITION DETECTION DEVICE AND ELECTRICAL POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/158918
Kind Code:
A1
Abstract:
This position detection device includes: a plurality of transmission-side elements that receive electric power and generate at least a magnetic field; a plurality of reception-side elements that output electric power due to the magnetic field generated by the plurality of transmission-side elements; a detection element that detects electromotive force generated by the plurality of transmission-side elements and outputs a signal corresponding to the detected electromotive force; and a processing device that, in a state in which electric power is supplied to the plurality of transmission-side elements and on the basis of the magnitude of a signal received from the detection element, determines information indicating the distance between the transmission-side elements and the reception-side elements, the degree of coupling between elements that form a set from among the plurality of transmission-side elements and the plurality of reception-side elements being a distribution that differs from that of elements forming another set in relation to said distance, and the degrees of coupling between the elements forming each of the sets coinciding at a specific distance.
