Resumo
© 2004-2012 IEEE.The aim of this work is to model Schottky diodes series rectifier for application in Radio Frequency Energy Harvesting (RFEH). A time-domain approach is proposed, including the reverse conduction of the diodes, which can significantly degrade the Power Conversion Efficiency (PCE) as the diode input power increases. The influences of the load, temperature, matching network and choke inductor have also been considered. The representativeness of the model was validated by means of computer simulations and experimental results.
