Research on Wireless Power Transfer System of Automated Guided Vehicle Based on Magnetic Coupling Resonance

This paper researches a wireless power transfer system of Automated Guided Vehicle (AGV) based on magnetic coupling resonance. Firstly, the mutual inductance equivalent model is given, and the transmission characteristics of the SP resonance compensation network are analyzed, and the relationship between the system voltage gain and the secondary quality factor is also analyzed. Then, according to the principle analysis, the wireless power transfer system in the AGV scene is designed. By properly configuring the resonance parameters, the inverter operates under soft switching conditions with low switching losses. And MATLAB simulation to verify the feasibility of the design parameters. Finally, the whole wireless power transfer system was built for charging 48V lithium battery.
