This paper proposes a method for analyzing power loss in a full-bridge LLC resonant converter based on the enhanced Time-Domain Analysis (TDA) technique. The proposed enhanced TDA method demonstrates that the power loss in an LLC resonant converter can be expressed through a complete equation. The necessary initial values are represented in equations, showing a deviation of less than 5% compared to simulation results. Furthermore, based on an 8.4kW full-bridge LLC resonant converter prototype, the proposed method and experimental values are compared in terms of efficiency across different loads, with a maximum error of 1.7% under light loads, while exhibiting highly similar values in other regions.
