| Abstract |
In most modem power electronic circuits, transformers are used to transfer energy. The size of the transformer is decreased by an increase of its operation frequency. As a consequence a very efficient point of operation is required in order to control the transformer temperature at its point of operation. In this paper a method to obtain the optimal and feasible layout for a high-frequency high-power transformer is presented. The increase of losses due to the skin and proximity effect are calculated. Also the hysteresis losses of the core are included to find the optimal transformer layout. A 10 kW 1 20 kHz transformer has been designed and tested. Its losses were determined with a calorimetric method. The results are compared with the predicted values. |
