Electron flux ⁇ V1 can circulate in the electromagnetic circuit part 110 because the core of the electromagnetic flux is implemented in a substantially rectangular shape.
  • the electromagnetic circuit unit 110 is effective in an electrically insulated double winding structure, but may also be configured in a single winding structure.
  • the number of windings on the input side (IN V1) and the number of windings on each output side (OUT1 V1, OUT2 V1) are equal to 1:1, To simplify the configuration, it is indicated as a core type. However, it is not limited thereto, and the number of windings of the input side (IN V1) and the number of windings of each output side (OUT1 V1, OUT2 V1) may be different from each other.

  • the first permanent magnet 120 has the same magnetic flux density and coercive force as the second permanent magnet 121, and the number of permanent magnetic fluxes radiated from the N pole of the first permanent magnet 120 is the iron core at the input side (IN V1). It is preferable that the number of magnetic fluxes equal to or slightly greater than the maximum number of electron fluxes generated in this saturation magnetic flux state is set so that they are radiated. In addition, it is preferable to set in consideration of the magnetic resistance of the closed circuit of the permanent magnetic flux. When the entire iron core of the electromagnetic circuit part 110 is saturated with an excessive number of permanent magnetic fluxes, the saturated magnetic flux state is maintained by the initial excitation current, and excessive current consumption and heat are generated.

  • the moving path of the permanent magnetic flux becomes long, which in turn increases the magnetic resistance of the closed circuit. Therefore, by installing the two permanent magnets 120 and 121 in series, the permanent magnetic flux is the same as when only one permanent magnet is installed, but the distance between the iron cores is reduced by 1/2, thereby reducing the magnetic resistance of the closed circuit of the permanent magnetic flux.

It is configured so that the magnetic resistance between them is remarkably low. Therefore, when power is not applied to the input side (IN V1) and current does not flow, most of the permanent magnetic flux from the N pole of the permanent magnet 120 goes to the S pole of the permanent magnet 121 through the input side (IN V1) path.
