Research on Near Field Electromagnetic Wireless Power Transmission Technology

This paper establishes a mutual inductance circuit model for the wireless power transmission (WPT) system, analyzes the impedance characteristics of the circuit, and takes the series compensation topology as the research object, analyzes the characteristics of the load power and transmission efficiency, and calculates and analyzes the mechanism of the eddy effect on the transmission of the resonant frequency of the underwater WPT, and designs the underwater WPT test circuit platform, in accordance with the optimized scheme, is realized about the distance 5cm, and the power is lkW underwater WPT. It provides theoretical guidance for the design and experiment of the WPT system.
