High Efficiency and High Power Quality Electrical Power Conversion

Diversified Technologies, Inc. (DTI) has been a pioneer in the development and deployment of high voltage DC power supplies and pulsed power systems based on series and parallel combinations of conventional silicon based devices, such as IGBTs. In this SBIR, DTI proposes to apply and extend its power supply and switching technologies to develop high voltage / high power converters that will meet the requirements of this SBIR, using combinations of power converter modules based on commercially available devices to accommodate input prime power at 4160 to 13.8 kV AC or 6 kV DC at multi-MW power levels. Under this SBIR effort, DTI proposes to analyze several candidate architectures to achieve this goal, and characterize one or more of these architectures. Approaches to maximize power conversion efficiency while minimizing weight and volume will be investigated. In Phase I, DTI will investigate various architectures to achieve the power conversion goals of this topic, and provide analytical and experimental data to support further architectural optimization.
