This paper presents a resonant isolated dc-dc converter for the LED backlight drive of the LCD TV module with a simple resonant half-bridge flyback converter power topology. The power topology structure of the proposed converter is isolated using the half-bridge flyback converter power topology with a transformer. The proposed converter switches complementarily its primary half-bridge switches and achieves high efficiency using the resonant circuit, composed of a resonant inductor and a blocking capacitor. The leakage inductance of the main transformer is used as the resonant inductor, and thus the proposed converter can be simplified. In this paper, the operational principle is analyzed, briefly, and a 100-W-class prototype is implemented based on the analysis. Then, it is shown that the proposed converter has good performance as a driver of the LED backlight drive of the LCD TV module through the experimental results of a 100 W prototype under a wide input voltage and load range.
