Power Loss Analysis of Full-Bridge LLC Resonant Converter

In this paper, a method of modeling the power loss of a full-bridge LLC resonant converter using the TDA (Time-Domain Analysis) method is proposed. Loss analysis based on TDA has higher accuracy than that of conventional FHA-based analysis. The proposed method shows the loss of a converter whose initial value is theoretically calculated for TDA analysis for a Full-Bridge LLC resonant converter. Also, compare the simulation value with the proposed method based on the prototype of the 10kw LLC resonant converter.
