Abstract
According to an aspect of the present invention, a wireless power transmitting apparatus of a wireless charging system includes a substrate, a first bonding layer formed on the substrate, a soft magnetic layer formed on the first bonding layer, a second bonding layer formed on the soft magnetic layer and a transmitting coil formed on the second bonding layer, wherein at least one of the first bonding layer and the second bonding layer includes a magnetic substance.
Claims18
A wireless power transmitting apparatus of a wireless charging system, comprising:
- a substrate,
- a first bonding layer formed on the substrate,
- a second bonding layer,
- a soft magnetic layer disposed between the first bonding layer and the second bonding layer, and
- a transmitting coil formed on the second bonding layer,
- wherein each of the first bonding layer and the second bonding layer includes:
- a first bonding agent,
- a first metal ribbon disposed on the first bonding agent,
- a second metal ribbon,
- a magnetic layer disposed between the first metal ribbon and the second metal ribbon, the magnetic layer including a magnetic substance the magnetic layer having a lower surface directly contacting the first metal ribbon and an upper surface directly contacting the second metal ribbon, and the magnetic layer being thicker than the first metal ribbon and the second metal ribbon, and
- a second bonding agent formed on the second metal ribbon,
- wherein a permeability of the magnetic layer included in each of the first bonding layer and the second bonding layer is higher than a permeability of the soft magnetic layer, and
- wherein a difference in the permeability between the magnetic layer and the soft magnetic layer is 100μ′ or more at a range of 100 to 300 kHz.
A wireless power receiving apparatus of a wireless charging system, comprising:
- a substrate,
- a first bonding layer formed on the substrate,
- a second bonding layer,
- a soft magnetic layer disposed between the first bonding layer and the second bonding layer, and
- a receiving coil formed on the second bonding layer,
- wherein each of the first bonding layer and the second bonding layer includes:
- a first bonding agent,
- a first metal ribbon disposed on the first bonding agent,
- a second metal ribbon,
- a magnetic layer disposed between the first metal ribbon and the second metal ribbon, the magnetic layer including a magnetic substance, the magnetic layer having a lower surface directly contacting the first metal ribbon and an upper surface directly contacting the second metal ribbon, and the magnetic layer being thicker than the first metal ribbon and the second metal ribbon, and
- a second bonding agent formed on the second metal ribbon, wherein a permeability of the magnetic layer included in each of the first bonding layer and the second bonding layer is higher than a permeability of the soft magnetic layer, and
- wherein a difference in the permeability between the magnetic layer and the soft magnetic layer is 100μ′ or more at a range of 100 to 300 kHz.
