# MATLAB Toolbox for Power Magnetics: Model and Optimization     This **MATLAB toolbox** allows for the **modeling and optimization** of power **magnetic components**: * medium-frequency **inductors** * medium-frequency **transformers** * computation of the **mass and volume** * extraction of the **equivalent circuit** * computation of the **core and winding losses** * **fast and accurate** semi-numerical methods * plotting of the winding and core geometries * brute-force **optimization** (parallel code) * flexible **object-oriented** design The following methods/functionalities are provided for the **core modeling**: * iGSE for the core losses (with locally fitted parameters from a loss map) * linear reluctance solver with 3D air gap models * multiple air gaps are allowed * multiphases components are allowed The following methods/functionalities are provided for the **winding modeling**: * mirroring method with inductance matrix and field evaluation (with/without air gaps) * solid wire windings (including skin and proximity losses) * stranded (Litz) wire windings (including skin and proximity losses) * multiple air gaps are allowed * multiphases components are allowed * model of the winding heads Currently, the following **components are implemented**: * inductors and two-winding transformers with shell-type windings * U-core, C-core, and E-core However, **additional components** can be added by implementing **abtract classes**. More specifically, the code could handle the following cases (without modifying the core classes): * multiphase components (transformers or chokes) * other winding geometries (core-type, matrix, etc.) * other core geometries (ELP, RM, etc.) * distributed airgaps ## Getting Started Two DC-DC converters are considered as examples: * a resonant converter (SRC-DCX) with a MF transformer * a bidirectional Buck converter (Buck DC-DC) with a MF inductor Both converteres are operating between 400V and 100V buses with a rated power of 5kW. The component geometry (core and windings) and the operating frequency are optimized. The example consists of the following files: * resonant converter (SRC-DCX) with a MF transformer * [run_src_dcx_1_single.m](run_src_dcx_1_single.m) - modelization of a single design * [run_src_dcx_2_combine.m](run_src_dcx_2_combine.m) - brute-force optimization of the component * [run_src_dcx_3_plot.m](run_src_dcx_3_plot.m) - optimization results (Pareo fronts * bidirectional Buck converter (Buck DC-DC) with a MF inductor * [run_buck_dcdc_1_single.m](run_buck_dcdc_1_single.m) - modelization of a single design * [run_buck_dcdc_2_combine.m](run_buck_dcdc_2_combine.m) - brute-force optimization of the component * [run_buck_dcdc_3_plot.m](run_buck_dcdc_3_plot.m) - optimization results (Pareo fronts) * [example_files](example_files) - definition of the parameters, materials, and waveforms ## Gallery ### Buck DC-DC Inductor <p float="middle"> <img src="readme_img/inductor_core.png" width="350"> <img src="readme_img/inductor_window.png" width="350"> </p> ### SRC-DCX Transformer <p float="middle"> <img src="readme_img/transformer_core.png" width="350"> <img src="readme_img/transformer_window.png" width="350"> </p> ### Pareto Fronts <p float="middle"> <img src="readme_img/buck_dcdc.png" width="350"> <img src="readme_img/src_dcx.png" width="350"> </p> ## Toolbox Organization The power magnetic toolbox contains the following packages: * [add_path_mag_tb.m](magnetic_toolbox/add_path_mag_tb.m) - add the toolbox to the MATLAB path * [core](magnetic_toolbox/core) - core reluctance and core losses * [core/README.txt](magnetic_toolbox/core/README.txt) - package documentation * [core/DATA_STRUCT.txt](magnetic_toolbox/core/DATA_STRUCT.txt) - data format documentation * [core/core_class.m](magnetic_toolbox/core/core_class.m) - main class * [core/core_lib](magnetic_toolbox/core/core_lib) - package internal classes * [core/core_example](magnetic_toolbox/core/core_example) - example/test files * [window](magnetic_toolbox/window) - winding window stray field and winding losses * [window/README.txt](magnetic_toolbox/window/README.txt) - package documentation * [window/DATA_STRUCT.txt](magnetic_toolbox/window/DATA_STRUCT.txt) - data format documentation * [window/window_class.m](magnetic_toolbox/window/window_class.m) - main class * [window/window_lib](magnetic_toolbox/window/window_lib) - package internal classes * [window/window_example](magnetic_toolbox/window/window_example) - example/test files * [component](magnetic_toolbox/component) - simulation of complete components (inductor or transformer) * [component/README.txt](magnetic_toolbox/component/README.txt) - package documentation * [component/DATA_STRUCT.txt](magnetic_toolbox/component/DATA_STRUCT.txt) - data format documentation * [component/component_class.m](magnetic_toolbox/component/component_class.m) - main class * [component/component_lib](magnetic_toolbox/component/component_lib) - package internal classes * [component/component_example](magnetic_toolbox/component/component_example) - example/test files * [sweep](magnetic_toolbox/sweep) - simulation of design sweeps (brute-force optimization) * [sweep/README.txt](magnetic_toolbox/sweep/README.txt) - package documentation * [sweep/get_sweep_single.m](magnetic_toolbox/sweep/get_sweep_single.m) - simulating a single parameter combination * [sweep/get_sweep_combine.m](magnetic_toolbox/sweep/get_sweep_combine.m) - simulating a many parameter combinations * [sweep/sweep_lib](magnetic_toolbox/sweep/sweep_lib) - package internal functions * [sweep/sweep_example](magnetic_toolbox/sweep/sweep_example) - example/test files ## Compatibility * Tested with MATLAB R2015b and R2021a. * Parallel Computing Toolbox. * Compatibility with GNU Octave not tested but probably problematic. ## Author **Thomas Guillod** - [GitHub Profile](https://github.com/otvam) This toolbox shares some files/ideas with the following repositories: * [mirroring_method_matlab](https://github.com/ethz-pes/mirroring_method_matlab) - ETH Zurich, Power Electronic Systems Laboratory, T.
