| Abstract |
The power supply devices for reducing the size of the LCD TV are increasingly required for high efficiency and highe power density. Recently, the LED backlight of the LCD TV comes into the spotlight for LCD TV, because the conventional CCFL backlight has difficult to use constantly according to the mercury restrictions. And In this paper, the LLC resonant converter using the planar transformer for slim-type LED backlight of LCD TV is presented and verified through an experimental prototype for 47 inch LCD TVs with LED backlight system. |
