Figure 3_SED-L

The SED library delivers pre-defined Modelica models that contain definitions of full electric drive systems – ready to be connected to a voltage supply and a mechanical load. These models enable the rapid simulation and analysis of complex electro-mechanical drive systems (e.g. dynamic simulation of a hybrid electric vehicle’s powertrain systems and components).

Components at different levels of abstraction include:

  • Accurate component models for the analysis of fast temporary effects (e.g. switching and transient effects due to electric energy storage elements)
  • Simplified system description models to enable fast simulations that still achieve accurate results for ‘big picture’ evaluations with minimal computational effort.


  • Simulation of energy storage, converters (power electronics) and controls for electric machines
  • Simulation of transient effects in electric drives
  • Supports the development and optimization of multiple control strategies
  • Ability to control machines from the Modelica® Standard Library
  • Quasi stationary models for different machine types
