Summary:As the screen size of LCD TV increases, an external electrode fluorescent lamp (EEFL) has been suggested to be applicable as backlight source for LCD TV In this paper, a complementary full-bridge RLC series-resonant inverter for external electrode fluorescent lamp (EEFL) backlight is analyzed and two different driving methods are investigated. From the characteristics of EEFL and the analysis of the inverter, the optimal design is obtained in two different input voltage specifications. Finally, some experimental results obtained from the laboratory are shown to validate the analysis and design.
