Temperature-Dependent Characterization, Modeling, and Switching Speed-Limitation Analysis of Third-Generation 10-kV SiC MOSFET

The temperature-dependent characteristics of the third-generation 10-kV/20-A SiC MOSFET including the static characteristics and switching performance are carried out in this paper. The steady-state...

An adaptive DC-bus stabilizer for single-phase grid-connected renewable energy source system

This paper proposes an adaptive DC-bus stabilizer for single-phase grid-connected voltage source converter (VSC) with small-scale renewable energy integration. To enhance converter's power density,...

Vehicular Integration of Wireless Power Transfer Systems and Hardware Interoperability Case Studies

Several wireless charging methods are under development or available as an aftermarket option in the light-duty automotive market. However, there are not a sufficient number of studies detailing the...


The Power Electronics and Electric Machinery Research Center (PEEMRC) is located at the National Transportation Research Center, which is designated as a DOE User Facility. The designation encourages collaborative efforts between the PEEM group, industry, and academia. The most advanced analysis, simulation, and design software is available to the PEEM staff to implement state-of-the art circuit and motor designs. PEEMRC provides a broad-based capability and an extensive list of equipment to build and evaluate power conversion circuit prototypes in-house starting from bare die and evaluating them. On the motors side, PEEMRC does research on electromagnetic characterization of motor materials, modeling and design, in-house prototyping and evaluation. These capabilities are provided at the user's expense. There are many ways to work with PEEM, including a cooperative research and development agreement, a work for others agreement, or a user agreement. Each agreement is developed based on a user's desire to protect research results or inventions.
