Data Channel

• Prepares the path for hardware in the loop
• Enables data exchange between model objects

Example parameter evaluated by a field solver
Example interaction with internal variables of
translated model

DC Zonal System

• Ship DC zonal power distribution system.

• The model from Purdue University includes
• 6 DC-DC converters (DCM implemented)
• 1 inverter feeding an induction motor
• 1 induction motor with Volt/per/Hertz inverter
  drive
• 1 DC load
• More than 300 variables

Conclusion

• A large ACSL model is successfully translated and
  runs with native VTB models
• VTB simulation results are very close to ACSL
• Data channel allows exchange of data with
  translated model
