Optimum Design of Transformer in High Frequency Switch Mode Power

The design of power transformer is almost the most important issue in switch mode power supply. If the transformer in switch mode power supply working at high frequency isn't designed carefully, the ultimate goal cannot reach. In this paper, we analyzed the design theory of high frequency transformer, and proposed a optimum design procedure which used in this case. With its help, we can decrease power loss and enhance the performance of the switch mode power supply.
