PEBB
  Virtual prototyping of PEBB components and assemblies is supported in VTB by PEBB component model development and concept visualization. Simulated data is presented in easy to understand formats using VTB's powerful visualization tools. Figure (a), shown below, illustrates the VTB Schematic Editor. It shows part of a PEBB phase leg with non-linear resonant components. Figure (b) shows the potential distribution inside one of the non-linear resonant capacitors. Figure (c) shows the output filter of a PEBB phase leg. Note how the inductor flux and capacitor charge is presented. VTB has the capability to present this information in real time.

VTB also supports thermal modeling and geometry based parasitic extraction. This relys on extraction of electrical parameters from the geometry, incorporation of those parameters into an electrical model of the PEBB, and simulation of the performance of that model. Figure (d) below shows the physical construction of an earlier PEBB power module, the parasitic capacitance between two conductors (as determined by the VTB spatial compute engine) and the location of the parasitic capacitance in the electrical schematic (shown in red). Figure (e) shows a simulated thermal distribution within a PEBB power module that uses SiC GTOs instead of the conventional Si IGBTs.

Another aspect of visualization is conceptual visualization. This allows a designer to construct a prototype in a virtual environment and be able to move components in 3D to understand the physical appearance of the new design. Figure (f) shows a 3-phase PEBB inverter using the new coordinate interconnects.
