Abstract: In this work, a voltage mode feedback controlled DC to DC boost converter is designed and simulated for a medium wave-based radio frequency (RF) energy harvesting system. The RF signal with an input power of 4 mW is converted to a DC signal which is stepped up and regulated by the boost converter. The DC to DC boost converter is controlled by a pulse width modulated circuit which generates a switching signal of frequency 100 kHz. A type-III compensator circuit is designed to regulate the output voltage at 3.3 V and 5 V which is suitable for low power applications.

Keywords: radio frequency; energy harvesting; boost converter; compensator; voltage mode control.
