WIRELESS POWER RECEIVING APPARATUS

摘要

PURPOSE: A wireless power receiving device is provided to improve conversion efficiency by receiving a radio frequency signal of a specific frequency band and changing the radio frequency signal into DC power. CONSTITUTION: A wireless reception unit(110) receives a radio frequency signal of a specific frequency band. The frequency of the radio frequency signal of the specific frequency band is 800MHz to 2.0GHz. An amplifier(120) amplifies the radio frequency signal of the specific frequency band. A rectification unit rectifies the radio frequency signal of k and changes it into DC power. A boosting circuit unit(150) amplifies each DC power. A combination unit combines the each power and outputs it.
