title = "Design and Optimization of Magnetic Integrated Matrix Transformer used for LLC Converter",
abstract = "The matrix transformer has good magnetic integration performance, lower parasitic parameters, and power loss, which makes it widely used in isolated DC/DC power modules. However, its low leakage inductance characteristic does not meet the requirements for the leakage inductance value in LLC circuit designs, especially when considering the integrated design approach for leakage inductance. Additionally, while there are various magnetic integration methods, comparative research on different solutions is relatively scarce. This paper addresses these issues by comparing the differences between two-integration and four-integration matrix transformer methods and selects the most efficient four-integration matrix transformer structure. And this paper also develops a parametric model of the leakage inductance under this matrix transformer structure by using the magnetic field energy method and proposes an integrated leakage inductance method. The conclusions were verified through finite element simulation finally.",
