一种新型隔离型双向DC-DC变换器通用稳态分析模型

Analysis modeling of isolated bidirectional DC-DC converters (IBDCs) is essential for effective performance analysis and design. To address the challenges posed by existing models in achieving accuracy, speed, and generality for optimization design purposes, this paper presents a novel generalized steady-state analysis model based on two-port network theory and frequencydomain analysis. The proposed model provides an analytical tool applicable to a range of IBDC topologies and modulation strategies, offering strong support in topology selection and automatic parameter optimization design. The effectiveness of this model has been verified through simulations and experiments, with the automatic parameter design software provided as an example to highlight its significant value and potential in IBDC design and applications.
