摘要： PROBLEM TO BE SOLVED: To provide magnetic cores which are reduced in size and whose magnetic properties are sufficiently utilized simultaneously. SOLUTION: Permanent magnets 31 are set close to the cores 21a and 21b of the reactor 30 of a step-up converter C, and the directions of magnetic fields of the permanent magnets 31 are set opposite to those of the magnets 31 in a step-up process. The flux densities in a step-up and a step-down process are shifted by the magnetic field of the permanent magnets 31. The upper limit of a flux density range in a step-up process is set equal to the saturation flux in a set-up process, and the lower limit of a flux density range in a step-down process is set equal to the saturation flux in a step-down process, whereby the feasible flux density scope of the core can be set to a full range from a negative saturation flux density to a positive saturation flux density, and the magnetic cores 21a and 21b can be reduced in size and their magnetic properties can be also sufficiently utilized at the same time.
