| Abstract |
In this paper, we will try to improve the efficiency of high frequency transformers. Loss is increased by increasing the frequency, so losses are reduced using various methods. There are several ways to reduce the loss, but in this paper we will focus on the iron core material of the transformer. We prepare several transformers made of four kinds of materials and measure and compare the losses. Measure the winding resistance in the high frequency region, confirm the skin effect and the proximity effect. |
