Conditioning System for an Electromagnetic Energy Collection Device

Abstract:

Power storage and conditioning today is very important for IOT devices, achieving high efficiency of conversion of RF energy into DC energy is essential to obtain a reliable voltage source that can be used to power low-power electronic devices. In this work it is shown that a higher output voltage is obtained by using a coupling stage between the source and the voltage multiplier. 1—and 4-stage voltage multipliers are designed and implemented with Schottky diodes in FR4 material, the same ones that are evaluated with various models of diodes and capacitances to select the one with the best performance. A considerable increase in voltage is obtained from - 5 dBm, managing to accumulate up to 4.5 Vdc quickly in an electrolytic capacitor with the 4-stage circuit.
