WIRELESS POWER RECEIVER FOR CONTROLLING WIRELESS POWER BY USING SWITCH

摘要

PURPOSE: A wireless power receiver for adjusting wireless power by using a switch is provided to obtain stable DC(Direct Current) output power by including a capacitor and a resonant-type inductor with the switch. CONSTITUTION: A power receiving unit(110) receives wireless power from a wireless power supplier. A rectifying unit(130) rectifies the wireless power into power of a DC waveform. A power adjusting unit(120) is electrically connected with the power receiving unit and the rectifying unit, forms a closed loop with the power receiving unit for a first period, and delivers the wireless power to the rectifying unit for a second period in order to adjust the size of the wireless power. A control unit(140) determines the first and the second periods.
