In this study, the 65" screen AMOLED TV has been carried out with a semi-bridge LLC resonant DC-DC converter design. The main objective of the design is to the optimal level of reliability and to the appropriate MTBF (Mean-time between failure - average life until failure). The reliability tests of the designed power card and critical circuit components cover the thermal, EMC and electrical tests have been carried out. Simulation analyses were also conducted using the PSIM program to study the work characteristics of the circuit at different switching frequencies. All of these comparisons and experimental studies have achieved a high level of reliability for over a decade with the value of 120.215 hours MTBF.
