Abstract The paper proposes a Z-type three-phase loosely coupled transformer, and the magnetic coupling of the primary and secondary coils are analyzed. The equivalent mutual inductance is obtained, and the equivalent impedance that mapping to the primary side from the secondary side is calculated. The model of wireless transformer is built in Maxwell to get the simulated parameters. The output characteristic is analyzed in PSIM. The results show the feasibility of three-phase WPT system and correctness of the analysis.
