| Abstract(in English) | In the magnetic coupling, the induced voltage based on the electromagnetic induction action by the interchanging of the magnetic flux between the coils is utilized. Generally, with free layout supply to arbitrary equipment and moving objects, uniformity of the magnetic field of the primary coil that generates magnetic flux is desired. On the other hand, author have studied this possibility by thinking that stepped magnetic field formation is effective for a new usage. Papers that researched nonuniformity magnetic field with respect to utility or mechanism are not found. The author has already tried to form a stairs like magnetic flux distribution by forming a single power transmission coil with multiple coils with parameters that can be numerically controlled. As a result, clearly different load voltage characteristics were confirmed depending on the position of the receiving coil. The load voltage characteristics have been demonstrated to be proportional to the equivalent coupling factor characteristics between the power transmitting and receiving coils, and the relationship between the numerical values of the parameters has been clarified by analysis, and useful knowledge of the formation of the desired inhomogeneous magnetic field has been obtained. This time, author tried two new methods aiming at the same characteristics as the stairs like magnetic field by the first method in order to increase the degree of freedom in designing the method of forming a nonuniformity magnetic field. As a result, equivalent coupling factor characteristics is confirmed in good agreement in all three methods, and accumulated useful knowledge of inhomogeneous magnetic field design. |
