17 MI or MR Technology? What is ideal solution MI (Magnetic Induction)? MR (Magnetic Resonance)? 중립국 PAGE 17

18 Wireless Power Technologies Magnetic Induction Variable Frequency Magnetic field mostly contained in between ferrite shielding Receiver and Transmitter Coils aligned and tightly coupled Magnetic Resonance Tx antennas are designed to create a charging area or field Magnetic field radiates outward and is not shielded Loose coupling provides spatial freedom PAGE 18

19 Inductive Wireless Power Transfer Power Transfer via Inductive Coupling at Short Distances (mm) Transmitter (Tx) and Receiver (Rx) coils are inductively coupled coils AC current in Tx coil generates magnetic field, which induces a voltage in Rx coil. Rx voltage may be used to power a mobile device or charge a battery Magnetic field concentrated in small volume between Tx / Rx User exposed to leakage fields only, which are minimized by shielding Improve coupling between coils by Matching coil sizes Flat interface surface to keep the distance small. Shielding and aligning coils Rx Surface Tx Surface Rx Coil I db/dt Shielding Distance Tx Coil Shielding PAGE 19
