碩士 === 國立彰化師範大學 === 電機工程學系 === 96 === ABSTRACT Due to serious reduction of power energy, energy regeneration is recommended by the government in recent years. In this thesis we design a radio circuit named wireless energy conversion system (WECS) to receive the electromagnetic energy from the air. The radio frequency (RF) is received and rectified as direct current to supply load or store in cell or capacitance. The WECS mainly consists of antenna, rectifier and charge circuit. To verify the possible feasibility of WECS, in this thesis we use the active tag as the load for charge-discharge experiments. Experimental results show that the WECS could reach 2.25V for charging 18 days and it could completely discharge during 190 seconds if implements with the resistance of 50 ohm. Therefore, the proposed circuit can reach the goal of recycle nature energy.
