WIRELESS POWER RECEIVING APPARATUS CAPABLE OF IMPROVING EFFICIENCY AND POWER DELIVERY USING MODULATION OF EFFECTIVE LOAD RESISTANCE OF RECEIVING END

WIPO Patent Application WO/2014/098279

A1

Disclosed are a wireless power receiving apparatus capable of improving power delivery using a modulation of an effective load resistance of a receiving end, and a wireless power delivery system using said apparatus. A receiving unit of the wireless power receiving apparatus receives power from a wireless power transmitter. A rectifying circuit unit rectifies the current outputted from the receiving unit and outputs the rectified current. A load resistance modulation unit receives a control signal including a duty ratio, controls the flow of the current applied from the rectifying circuit unit according to the received control signal so as to vary the size of the effective load resistance, and increases the size of the equivalent resistance so as to improve efficiency.
