摘要：

LLC resonant converters are widely used in power supplies. For product design needs to estimate voltage stress, current stress, and power loss analysis. An accurate analysis is required to assist in the development of the product. This paper utilizes the LLC resonant converters to analyze the current waveform in each interval of the resonant tank. The waveform is analyzed to estimate the loss of each component. In this paper, we compare the mathematical modeling methods of TIA and FHA. Moreover, the paper used the simulation to verify the waveform of the mathematics model. This paper implements a prototype in a 48V-12V DC-DC high power density LLC resonant converter.
