Abstract
With the increasing demand for miniaturization and lightweight of power supply equipment, high power density has become the development trend of power electronic converters, as well as in photovoltaic grid-connected applications. LCL filter is the most widely used passive filter in grid-connected inverters. However, the traditional LCL filter has low core utilization and large volume redundancy. Based on the above problems, this paper proposes a matrix coupled inductor filter and optimizes the core volume. Finally, the simulation circuit of the matrix coupled inductor filter is built by using MATLAB/Simulink simulation platform, and compared with the traditional LCL filter, the feasibility and effectiveness of the proposed filter are verified.
