Adaptive Feedback Magnetic Coupling Resonant Wireless Power Transmission System

This article proposes a design method for an adaptive feedback magnetic coupling resonant wireless energy transmission system. Compared with traditional wireless energy transmission systems, which add a DC-DC converter after the receiving coil to stabilize the output voltage, this article designs a feedback communication circuit for the adaptive system: using an infrared transceiver shaping circuit to receive the output voltage signal from the energy output terminal, and feeding it back to the energy transmission terminal through MCU to regulate the operating frequency of the circuit, thereby stabilizing the output voltage and ensuring the stable operation of the circuit system. Finally, in the circuit construction and testing of the system, under the requirement of input DC 100V and output DC 100V, the power transmission efficiency reached 90%.
