A Study of High-Efficiency/High-Density Phase Shift Full Bridge Converter with Low Profile Two-Transformer Structure

Interest in environmental protection, particularly low-carbon policies, is rapidly increasing. Along with the development of various technologies and functions in the automobile industry, the electric vehicle market is also experiencing significant growth. One area of active research in electric vehicles is the development of high-efficiency and high-density Low DC-DC Converters(LDC), which convert the high voltage of the main battery into a low voltage of 8-16V. This paper focuses on the study of an LDC based on a Phase Shift Full Bridge (PSFB) Converter with a low height Two-Transformer structure, with the goal of achieving high efficiency and density of the LDC.
