Abstract

This paper presents Wireless Power Transfer of Devices Using Non-Radiant/Radial Structure. Radial and non-radio-radio-type radio charging receiving station physical and layout , measurement was carried out. High-efficiency Adaptive Rectifier operating in wide receiving power range, Low-Drop-Out Voltage Regulator for rapid charging, and Analog-to-Digital Converter for communication and power control have been developed. The core of wireless energy technology is the efficiency of RF-DC Converter. In the computer simulation results, the maximum efficiency of the radial radio charging reception was 47.19% at 0 dBm of input power and 88.62% at the non-radio charging reception. The use process is CMOS process 180nm and the chip area is 5000um X 2450um.
