Coupling component placement and parametrization - Ideal Transformer based couplings

This section describes the coupling component placement procedure and provides some general rules and tips for successful partitioning.

Note: Offline simulators, like TyphoonSim, use a variable simulation step in their simulations, so real-time constraints are not a concern. As a result, model partitioning is not required for offline simulations because there is no need to split the model to improve computational performance within a fixed time frame. All of the following descriptions are related only to real-time/VHIL simulation.

Note: An interactive overview of the concepts and/or capabilities described here are available as part of the HIL Specialist 2.0 certification program on HIL Academy, as well as in the video Knowledgebase.

Correct placement and parametrization of coupling components is crucial for simulation stability and accuracy. There are a few steps that can help in correct circuit partitioning:

Check if there is a need for circuit partitioning
- identify which components have to be in different sub-circuits (different cores or devices)
Place the coupling components
- Find the best spot for the coupling
- determine the correct rotation of the coupling
Analyze if there is a need for snubbers
- set the required snubber option (dynamic/fixed, resistive, capacitive, inductive)
- set the snubber value
Analyze the stability of coupling components
