Princeton MagNet is a large-scale dataset designed to enable researchers to model magnetic core loss using machine learning to accelerate the design process of power electronics. The dataset contains a large amount of voltage and current data of different magnetic components with different shapes of waveforms and different properties measured in the real world. Researchers may use these data as pairs of excitations and responses to build up analytical magnetic models or calculate the core loss to derive static models.

Documentation

The web application for Princeton MagNet uses the magnet package, a python package under development where most of the functionality is exposed. Before magnet is released on PyPI, it can be installed using pip install git+https://github.com/PrincetonUniversity/magnet.

Please pip install mag-net and pip install . in the magnet folder before running streamlit.
