摘要：

This article analyses and presents an LLC resonant converter with a high power factor for LCD-TV applications. It integrates the advantages of power factor correction and the LLC resonant converter. It can improve not only power quality but also circuit efficiency. Since the power factor corrector is used in the first stage of the LLC resonant converter, it is suitable for wide input voltage range application. On the basis of the resonant behaviour, zero voltage switching is achieved for the power switches and ZCS is achieved for the rectifier diodes. An experimental prototype of 90-260V(rms) input and 12V/10A and -12V/10A outputs with 92.6% efficiency for 32 '' LCD-TV application is built in the laboratory to verify the operation principle of the adopted converter.
