- 回顾一个多世纪以来电力工业和电力系统的发展,深感由于经济发展和技术进步带来的巨大变化。上世纪的80~90年代,是电力系统的初创时期。据记载,1882年在美国纽约建成了世界第一个完整的电力系统。这是一个由发电机、电缆和负载组成的直流电力系统。然而由于直流输电系统的局限性,人们转而研究交流输电技术,并在上一个世纪之交,确立了交流输电系统进一步发展和应用的基本取向,从而带来了本世纪交流高电压输电和电力系统的大发展。从本世纪初到60年代末,最高交流输电电压从12.44千伏和60千伏提高到735千伏和76

- 在大功率DC/DC开关电源中,为了获得更大的功率,特别是为了得到大电流时,经常采用N个单元并联的方法。多个单元并联具有高可靠性,并能实现电路模块标准化等优点。然而在并联中遇到的主要问题就是电流不均,特别在加重负载时,会引起较为严重的后果。普通的均流方法是采取独立的PWM控制器的各个模块,通过电流采样反馈到PWM控制器的引脚FB或者引脚COMP,即反馈运放的输入或者输出脚来调节输出电压,从而达到均流的目的。显然,电流采样是一个关键问题:用电阻采样,损耗比较大,电流放大后畸变比较大;用电流传感器成
