摘要
在开关电源的设计中,功率变压器的设计是极为关键的,尤其当工作频率提高后,若没有新的变压器优化设计方法,是无法达到提高整个电源功率密度的目的。该文在深入分析了高频变压器的设计原理后,提出了一种有效的优化设计方法,可降低变压器的功率损耗,提高开关电源的效率。
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抰 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.
