Power Electronic Building Blocks
The VTB project supports development and applications of Power Electronic Building Blocks (PEBBs). PEBBs are solid state components of the next-generation electronic power converters in 3rd generation development. PEBBs will be able to serve in multiple capacities, depending only on how the controller is programmed. A power controller based on PEBB technology might be configured as a DC to AC inverter, a synchronous rectifier, or a motor controller simply by changing the controlling software. PEBBs incorporate arrays of high-power switches, microprocessors and appropriate passive waveshaping components. The VTB supports the PEBB program in three ways:
Virtual prototyping
of the PEBB is important because of the many interactions that may occur. For instance,
the PEBB incorporates a digital computer and associated low-power communication links, but
also high-current and high-voltage switches that can emit electro-magnetic energy that
interferes with logic-level signals. Furthermore, the activity of a PEBB involves many
different technologies -- digital, analog, thermal, and mechanical. These different
aspects of the system are most readily modeled using different tools. A purpose of the VTB
is to combine into one simulation, the models creating by using different modeling tools.
Download some mpeg files, which are visualizations of an early PEBB power module
assembly (a) and the assembly of conceptual PEBB phase legs that use the coordinated
interconnect for the passive components. These videos were created using some of the
advanced visualization capabilities of the Virtual Test Bed.
