随着人们对照明节能的日益重视 ,倡导绿色照明以及美国等国对节能法的推动 ,作为照明电器重要组成部分的高频可调光电子镇流器得到迅速发展。本文介绍Fairchild公司开发的电流反馈调光电子镇流控制IC—KA75 34,以及与KA75 2 6功率因数校正IC共同构成的荧光灯调光电路
As people pay more and more attention to energy-saving lighting, advocate green lighting and the promotion of energy-saving law in the United States and other countries, the development of high-frequency dimmable electronic ballast as an important part of lighting appliances has been rapidly developed. This article describes Fairchild’s current feedback dimming electronic ballast control IC-KA75 34, and KA75 2 6 power factor correction IC together constitute a fluorescent lamp dimming circuit
