In our simulations, we use our own models for all relevant simulation elements:   power switches (power modules), DC link capacitors, modulators, magnetic cores, equivalent circuits for motors, etc. This ensures that all crucial components are included in the models - and no unknown or unclear parts or command lines - with unknown and possibly unpredictable and from outside unexplainable reactions.

The more complex a model is assembled, the more difficult and extensive the tests for verifying the model are.

Increasing complexity also increases the runtime in the simulator - and the risk of convergence problems.

All models are designed according to the particular environment or requirement:

The performance switches are similar in behavior to Infineon's power modules with IGBT chips.

For SiC technology, on the other hand, the behavior of SiC-MOSFETs and power modules are approximated.

Our models converge well and are fast - fast enough to be able to simulate large systems, such as Double-Inverters, Inverter-DCDC combinations or 3-phase on-board chargers within a reasonable time frame.

Despite the high speed, the simulation results are in good agreement with measurements - thus allowing quite accurate predictions, e.g. about the effect of modifications.

Many models support a modular concept in their design, thus allowing fast adaptations to new systems.
