Abstract
The project explores a pragmatic approach to achieve balanced current sharing among paralleled power modules by optimizing external layout of the system using Genetic Algorithm (GA). The goal is to enable detection of impedance imbalances in complex system layouts, making it easier for designers to visualize and mitigate issues during the early stages of development. A key feature of this project is the use of FastHenry, an open-source software tool. Its accessibility and transparency provide users with full control over design and operation, while its seamless integration with MATLAB, the workflow becomes more efficient, enabling automated simulations, equation solving, and interactive visualizations. For a fully open-source alternative, Python can be used as well to achieve similar integration. To validate the tool’s output, several layout variants with varying complexity were generated using the algorithm and tested using a Double Pulse Test (DPT) setup at KK Wind Solutions’ facility. Further developments shall include improving the accuracy of the Fast Henry model, refining the optimization tool for convergence speed and making it user-interactive.
