摘要
设计一种基于磁放大器的ATX电源,其特征是利用磁放大器实现对输出电压进行精确地调节,获得高稳定度的+3.3V输出电压,可大大简化开关电源二次电路的设计。首先详细分析磁放大器稳压电路的基本原理及电路设计,然后介绍了145W多路输出式PC开关电源的主电路设计。
A type of ATX power supply based on magnetic amplifier is designed in this paper. The power supply can realize the accurate adjustment of output voltage through the magnetic amplifier and thus obtain ＋3.3V output with high stability. Our method can significantly simplify the design of secondary circuits. In the paper, we analyze the basic principles and the design of magnetic amplifier circuit in detail and then introduce the design of main circuit for 145W multi-output PC switching power.
