Title:
CURRENT DETECTION ELEMENT, POWER TRANSMITTING DEVICE, AND POWER TRANSMITTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/190290
Kind Code:
A1
Abstract:
A current detection element (1) is provided with: a laminate (10) in which a plurality of insulator layers are laminated; a main line conductor (11) formed on the laminate (10) and extending in one direction; a coiled current detection conductor (12) that is formed on the laminate (10) and is magnetically coupled to the main line conductor (11); and an electrostatic shielding conductor (13A, 13B) that is formed on the laminate (10) and is connected to a ground. In a planar view from the winding axis direction along the winding axis of the current detection conductor (12), the electrostatic shielding conductor (13A, 13B) overlaps with at least one of the main line conductor (11) and the current detection conductor (12). Provided as a result are a current detection element that accurately detects a high-frequency alternating current flowing in a line, and a power transmitting device and a power transmitting system that are equipped with the current detection element.
