Model and Analysis of Multi Level Multi Frequency RF Rectifier Energy System for Low Power Supply Application Device
Abstract: Sustainable energy
for the mobile electronic devices always needed during the energy storage batteries
capacity in the mobile electronic devices are limited for a few hours for the
usage time. To get a long lasting operating time from the mobile electronics
equipment sets, the energy source should alwaysbe connected into the device. In
this paper, we were proposed a charging energy method via wireless operation
supply using the microwaves (RF) radiated by the air multi-frequency. The RF to
DC rectifier circuit is a major component for changing the RF wave to an
electronic current (DC). The Dickson models were used as an approach to
superiority includes a simple series, low DC ripple factor, etc. The design, analysis,
and the experimentation from the rectifier circuit have been conducted and
presented in this paper. In the measurement, the mobile electronic devices
placed at a distance about 5 meters from the energy source with the system
voltage DC 3.7V, and have been obtained at the working frequency between 825 -
960MHz with the PCE values 12-33%, and a ripple factor of ± 0,01%. The charging
time energy is needed about 4 hours at the research trial room, and about 11
hours outdoor had been observed. Based on these results, the wirelessly energy
charging method for the mobile electronic devices is a potential methods to
resolve the sustainable energy issue and the green technology supporting with the
most programs.
