Abstract
Nowadays, power supplies for LCD TV of larger and slimmer screen size are required to have high power density and high efficient characteristics. In order to meet these requirements, Multi-phase interleaved LLC resonant converter is applied for increasing power density and reducing the current rating in the used devices. In this paper, gain characteristics and the experimental results of the proposed two-phase LLC resonant converter which implemented by the simple control circuit are verified based on the theoretical analysis and the 300W experimental prototype.
최근 대화면 및 슬림화를 위한 LCD TV의 전원장치는 고집적화와 고효율에 대한 연구가 이슈가 되고 있고, 이를 위해 Multi-phase LLC 공진컨버터가 연구되고 있으며 본 논문에서는 제어회로를 간단화 하면서 300W Two Phase Interleaved LLC 공진컨버터를 제안 적용한 실험결과에 대하여 서술하였다.
