MAGNETIC SHIELD FOR WIRELESS POWER RECEIVER MODULES AND WIRELESS POWER RECEIVER MODULES INCLUDING THIS MAGNETIC SHIELD

Abstract

The invention relates to a magnetic shield for a wireless power supply receiver module and a wireless power supply receiver module incorporating this magnetic shield. The magnetic shield for a wireless power supply receiver module, according to a typical design of this invention, is intended for a wireless power supply receiver module capable of performing wireless power sharing (WPS) functionality and having an overall thickness of 150 µm or less. The magnetic shield comprises: a first plate (111) made of magnetic material to be magnetically shielded; and a second plate (112) comprising multiple layers formed as a single layer on one surface of the first plate by bonding an adhesive layer, wherein the second plate is relatively smaller than the first plate while having a saturation magnetic flux density equal to or greater than twice the saturation magnetic flux density of the first plate.
