Collaboration with VTech and UW-Milwaukee enables this research to leverage integrated power electronics building block (iPEBB) design and functionality, and EMI HF modeling. The research will analyze a common mode (CM) reduction method designed to achieve the conducted emission (CE) limits in MIL-STD-461G with reduced passive filters.

Over the course of this project, the research team will perform hardware prototyping on EMI to produce different iPEBB architectures and create physics-based models with CM. Upon achieving the objectives of this research and analysis, future work is anticipated for AC/DC and DC/AC conversion modules for hardware and models, and system-level EMI characterization.

This research to create the digital twin of a microgrid to validate and update with hardware physical twinning will take advantage of physics-based models to run simultaneously a virtual twin and add AI capabilities by utilizing a field programmable gate array (FPGA).

In collaboration with resources from the USMC and UW-Milwaukee, the research team plans to leverage foundational work in digital twinning to develop bidirectional DC/DC converter for battery interface, model distributed energy resource and validate models, using measured parameters to update the virtual twin.

The testbed can be utilized to perform EMI stress tests on each component, particularly the control and gate drive circuit boards, within the Navy's iPEBB. This non-destructive approach will help identify potential EMI vulnerabilities and assess EMI susceptibility. The proposed toolset can significantly enhance system EMI immunity and reduce the system development cycle.

To achieve energy resilience on naval facilities, this project will address the microgrid need to accelerate integration and training for design and implementation of microgrids across the Navy. By analyzing its performance, it anticipates power system resilience can be increased in small increments, which can support the DoD fight against climate change by generating renewable energy resources.

Working closely with end users at Naval Station Rota, NAS Sigonella and Souda Bay, the project team will design and install physical nanogrids, as well as write the RFP and obtain funding sources. Control Hardware-in-the-Loop will be set-up and maintained at UW-Milwaukee to test out changes to the scalable, zonal system in the field.
