I have implemented several MATLAB codes for power system load flow analysis methods, including 

• Gauss-Seidel (GS), 

• Newton-Raphson (NR), 

• Decoupled Newton-Raphson (DC-NR), and 

• Fast Decoupled Newton-Raphson (FDC-NR). 

These are available collectively on GitHub and MATLAB File Exchange for easy access and download. 

I’ve uploaded a collection of magnetic design codes for power converters based on the principles from Fundamentals of Power Electronics by Robert W. Erickson and Dragan Maksimović. These MATLAB implementations are useful for designing inductors and transformers in DC-DC converters. You can find the complete repository on GitHub. For learners and researchers, I highly recommend the Coursera course-Magnetics for Power Electronic Converters. For a deeper and more practical understanding of efficient magnetic design, I highly recommend exploring the Ridley Engineering Magnetics resources, which are free to download. You may also consider using RidleyWorks, a powerful tool specifically tailored for magnetic component design.
