Benefits of technology

[0023]According to an embodiment of the invention, it may be possible to increase the effective permeability of the wireless power transmitting apparatus and the wireless power receiving apparatus, and to increase the inductance of the wireless power transmitting apparatus and the wireless power receiving apparatus. Therefore, the efficiency of power transmitting / receiving between the wireless power transmitting apparatus and the wireless power receiving apparatus can be increased.

Problems solved by technology

Due to a limitation related to size of the coil which is wound, there is a limitation in regards to achieving a desired level of the effective permeability.
In particular, there is a problem related to the wireless power transmitting / receiving apparatus applied to a vehicle in that it is difficult to apply a high-permeability-pellet to a soft magnetic layer due to vibration or temperature variation characteristics.
Thus, there is a limitation in terms of being able to increase the permeability by increasing the thickness of the soft magnetic layer.

Embodiment Construction

[0036]While the invention can allow various modifications and alternative embodiments, specific embodiments thereof are shown by way of example in the drawings and will be described. However, it should be understood that there is no intention to limit the invention to the particular embodiments disclosed, but on the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

[0037]It will be understood that although the terms including ordinal numbers such as “first,”“second,” etc. may be used herein to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a second element could be termed a first element without departing from the teachings of the present inventive concept, and similarly a first element could be also termed a second element. The term “and / or” includes any and all combination of one or more o...
