摘要
在E系列S1240程控交换机的开关电源电路中,采用高频磁放大器作为稳压元件。磁放大器有多种规格,分别由两种尺寸的方形坡莫合金80薄带卷绕铁心制成。本文报导了这种铁心的研制过程、主要磁特性及快速检验方法等。
Two toroidal Strip-wound cores made of square permalloy80 are used for high frequency magnetic Amplifiers. Which have many kinds of specification and are used as stabilized Voltage Components in the Switched-Mode power supply circuit of E system S1240 program-controlled exchanger. The research and development process, the main magnetic properties and the fast testing method of these toroidal strip-wound cores are Introduced in this report
