Design Based on Wireless Energy Transfer System of Self-Resonant

Abstract

Wireless Power Transfer can use electrical equipment to get rid of the bondage of wires. Taking single-chip microcomputer STC12LE5A60S2 as the control core, a medium-distance radio energy transmission system is designed by using electromagnetic coupling resonance technology. Royer self-oscillating circuit is designed to generate sinusoidal oscillation signals of a certain frequency. Electromagnetic energy is transmitted through LC resonance circuit, and electromagnetic energy is received by LC resonance circuit at the receiving end through rectification and stabilized voltage output, realizing wireless energy transmission. The system also designed a wireless energy relay module, effectively increasing the distance of wireless energy transmission up to 15 cm. The power detection chip INA219 is used to collect the output voltage and current, and the LCD LCD12864 is used to display the output voltage, current and transmission time.
