Abstract
A wireless charging system was designed by combining magnetic resonance coupling and radio frequency energy harvesting. Resonant coils and a 5-stage charge pump were constructed for transmission. rectification and amplification of an AC signal at low voltage. The system operated at a resonant frequency of 4.36 MHz. Two separate charge pumps were made. Compared to that which utilized a 1N60 Germanium diode, the gain of the charge pump with an HSMS- 2820 Schottky diode was 122% higher. The system was capable of transmitting power at a distance of 4.0cm with —8.61% efficiency. Upon placement of an auxiliary coil between the source loop and the device coil, the efficiency of the system was raised to —29.53%. Power was successfully transmitted up to a distance of 21.0cm.
