Abstract
Official abstract text for this publication.
A coil unit includes a coil and an accommodation case accommodating the coil. The coil is formed of a coil wire wound around a winding axis. A hollow portion is formed in a position in which the winding axis passes. The coil includes an outer peripheral portion located in an outer peripheral edge of the coil, and an inner peripheral portion located along an inner peripheral edge of the coil. A voltage on the inner peripheral portion is higher than a voltage on the outer peripheral portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A coil unit comprising: a coil formed of a coil wire wound around a winding axis, a hollow portion being formed in a position in which the winding axis passes; an accommodation case accommodating the coil; a metal member; a first power line connected to a power storage device; a second power line connected to the power storage device; a first capacitor and a second capacitor connected in series to each other between the first power line and the second power line; and a rectifier connected to the first power line and the second power line, the rectifier including: a first element and a second element connected in series to each other between the first power line and the second power line; and a third element and a fourth element connected in series to each other between the first power line and the second power line; the coil including: an outer peripheral portion located in an outer peripheral edge of the coil, the outer peripheral portion is connected between the first capacitor and the second capacitor; and an inner peripheral portion located along an inner peripheral edge of the coil, the inner peripheral portion is connected between the first element and the second element, a voltage on the inner peripheral portion being higher than a voltage on the outer peripheral portion. 2. The coil unit according to claim 1 , wherein the metal member is a fastening member configured to fasten the accommodation case to a mount surface, and the fastening member is disposed outside the outer peripheral portion of the coil. 3. The coil unit according to claim 1 , wherein the accommodation case includes a first cover member and a second cover member, and the metal member is a cover fastening member configured to fasten the first cover member and the second cover member to each other. 4. The coil unit according to claim 1 , further comprising a device connected to the coil, wherein the metal member is a metal case accommodating the device and accommodated in the accommodation case.
