ENERGY HARVESTING SYSTEM USING VARIABLE ADJUSTMENT OF CAPACITOR TO PREVENT SATURATION OF MAGNETIC FLUX DENSITY OF CORE AND OPERATION METHOD THEREOF

摘要

The energy harvesting system according to this embodiment is a secondary circuit in which a second voltage is generated according to an induced electromotive force by a primary circuit that transmits a first voltage including an alternating current (AC) component of a predetermined size. ; a core magnetically associated with the primary circuit and the secondary circuit according to a predetermined turns ratio; a capacitor variable adjustment circuit having one end connected to one end of the secondary circuit and transmitting a first output voltage associated with the second voltage through the other end; a plurality of diode circuits connected to the other end of the capacitor variable adjustment circuit and the other end of the secondary circuit; and a control device for measuring a second output voltage transmitted from the plurality of diode circuits and adjusting a capacitance for the capacitor variable adjustment circuit based on the measured second output voltage.
