高频开关电源主要磁性元件的设计

The Design of Main Magnetic Components in High-frequency Switching Power Supply

本文重点研究高频开关电源的磁性元件的设计,在高频开关电源设计过程中需要解决的一个关键问题,就是热的问题;而热主要来源是磁性元件,如何解决磁性元件的损耗及发热问题,减小磁性元件的尺寸也成为该课题的一个关键问题。所以磁性元器件的设计自然成为整个设计关节中相当重要的一环。

This article focuses on the design of the magnetic components for the high-frequency switching power supply. The key issue in high-frequency switching power supply design is the heat problem. As the main sources of heat are magnetic components, how to reduce the toss and heat of magnetic components becomes the most important point on the way to miniaturization of these components. Therefore, the design of magnetic components naturally becomes a very important joint in the design of high-frequency switching power supply.
