MULTI-NODE WIRELESS POWER TRANSMISSION SYSTEM AND WIRELSS CHARGEABLE DEVICE USING MAGNETIC RESONANCE INDUCTION |
摘要 |
PURPOSE: A multi-node wireless power transmission system and a wireless chargeable device using magnetic resonance induction are provided to selectively charge a target device by receiving information from a plurality of wireless chargeable devices through a wireless power transmission device. CONSTITUTION: A power management unit(220_1) comprises a matching network(221), a rectifier(222), a power control switch(223), and a DC-DC converter(224). The DC-DC converter is connected to an external load of the power management unit. The power control switch receives an ON/OFF switching signal from a control unit. The matching network aligns frequency in order to induce resonance between a wireless chargeable device and a wireless power transmission device and implements impedance matching between a receiving antenna(210) and a wireless chargeable device.
