Title:
COIL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2014/188662
Kind Code:
A1
Abstract:
A coil structure is configured, such that an occurrence of a surge voltage is suppressed, from a magnetic core (101), a coil (102), and link conductors (103a, 103b) which are short-circuit conductors which configure closed circuits. The magnetic core (101) further comprises a core leg (110). The coil (102) is positioned in the circumference of the core leg (110). A primary magnetic field is emitted in the core leg (110) by an electrical current flowing in the coil (102). The link conductors (103a, 103b) are positioned in locations which are in contact with the coil leg (110) and which link with the primary magnetic field. The coil (102) and the link conductors (103a, 103b) are electrically insulated from one another.
