Recently, the inductor has become an important component in order to obtain high performance of the electric devices such as mobile telephone, and further improvement of the inductor performance is needed. Especially, the inductance under superimposed DC current is one of key properties for the application using inductor. However, it is difficult to satisfy such high performance only by an improvement of the magnetic material. Therefore it is required to establish the inductor shape design technique considering with the magnetic material properties in order to improve the inductor performance. In this paper, the shape optimization method of inductor using probabilistic optimize algorithm is discussed and the availability of this method is examined through the comparison between the calculation and the experiment. As a result, ∼60 % downsized shape can be derived from this optimization method maintaining the same performance of the original inductor.
