In this study, a multiple output quasi-resonant flyback topology for 140 – 275 V AC input voltage range, up to 120 W output power with 12.5 V and 60 V output voltage for television application has been presented. In the presented converter, current design of fixed-frequency flyback design has been changed with proposed quasi-resonant flyback design and design parameters are discussed. Moreover, thermal analyses and energy efficiency measurements have been carried out. In conclusion, it has been seen that in terms of thermal analyses and energy efficiency, quasi-resonant flyback with multiple outputs for a television power supply application is a viable option. In this study, it has been observed that proposed converter has reached 86% efficiency at 75% load condition with 275 V AC mains input.
