Single Stage SST Development, FREEDM Core Project

Sponsored by NCSU Future Renewable Electric Energy Delivery and Management Systems Center (FREEDM)

Wensong Yu
Iqbal Husain
Srdjan Miodrag Lukic

Project runs from 06/01/2022 to 06/30/2023
$50,000

Research in single stage solid state transformer (SST) development. A challenging aspect of SST development is maintaining high efficiency while improving the power density and reliability. The project goal is to achieve 99% efficiency for a 20kW single-stage AC-SST at module voltage ratings of 480V input and 480V output and to explore the feasibility and scalability for such technology at 35kVac and 10MVA levels. The goal will be achieved with simplified modular topology and a novel control method that will provide soft-switching operation over the entire operating range.
