Research on Electromagnetic Coupler in Deep-sea Inductive Power Transmission System

Inductively coupled power transmission technology (ICPT) is the recent rise of a new type of power transmission mode. In view of the influence of current turbulence on ICPT system transmission performance in the deep sea, ANSYS finite element simulation software is used to analyze the changing trend of coupling coefficient and inductance parameters in different gaps of the electromagnetic coupler with the eccentricity. Mutual inductance equivalent circuit with compensation capacitor is designed to calculate and analyze influencing factors of system power and transmission efficiency under resonance conditions. Simulation study is also made for the changing rule in which system power and transmission efficiency vary with input voltage, load resistance, frequency and turns per coil so as to provide reference for the optimization design of ICPT transmission system in the marine conditions.
