Grid-Integrated Electric Drive Analysis for The Ohio State University
NREL performed thermal management analysis and simulations on a high-performance, high-speed drive—developed by The Ohio State University (OSU)—that is capable of integrating with electric grids.
The proposed work can be considered as a pilot study for the future generation of energy efficient, high power density, high-speed integrated medium/high-voltage drive systems. If successful, the proposed project will significantly advance transformer-less drive technologies for a range of industries and motor applications.
For the thermal management analysis and simulations, NREL:
- Developed 3-D, finite element analysis (FEA) thermal models for commercially available power modules to incorporate into the system design and to identify heat sink requirements
- Performed analysis of commercially available air-cooled heat sinks
- Prepared preliminary system thermal model and shared system-level impacts of heat sink, fan, and system layout design options
- Developed computational fluid dynamics (CFD) models for analysis of alternative air-cooled, heat-sink designs and fans.
The research supported OSU's project milestone for the U.S. Department of Energy Advanced Manufacturing Office (AMO). Learn more about AMO.
