Engineered Systems Thrust: IPEMs-based Power Conversion Systems (IPEM-PCS)
Leader: Dushan Boroyevich, Virginia Tech
The goal of this thrust is to develop an integrated system design
approach to the electric energy processing systems based on IPEM
and to explore the broader impact of the CPES-developed technologies
on the electrical energy usage in our society. The IPEM-PCS thrust
is formulated to validate the system integration concept by implementing
a complex electronic power distribution test bed using IPEM and
IPEM-related technologies developed in other thrusts. The two main
focuses are: 1) Develop demonstrative converters and system test
beds encompassing advanced component, module, and integration technologies
from CPES and elsewhere. 2) Develop integrated and generalized
methodology and tools for converter system modeling, analysis,
design, and optimization.
The figures below show an integrated telecom Distributed
Power System (DPS) test bed based on an integrated active switching
module (active IPEM), an integrated energy storage passive module
(passive IPEM), and an integrated EMI filter (filter IPEM). The
integrated converter exhibits a simplified system design and assembly
effort, and resulted in significant improvement in performances
and power density. Other significant accomplishments include the
development of an integrated converter design and synthesis methodology
combining together the software tools of circuit analysis, circuit
and structural layout, electromagnetic analysis and parameter extractions,
thermal analysis, and optimization. Currently, an electronics power
distribution system test bed is being developed that is representative
of wide range of applications, from server farm and data center,
to vehicular and alternative energy systems.
