Simulink model for the analysis and development of hybrid and electric vehicle power networks.
Task
Create a model that contains the most significant components of a low voltage electrical network, such as alternator, rectifier, loads and battery, designed in form of sub-models. The power network model had to be designed in such a way that the single sub-models can be adjusted or completely replaced following the modular ideology.
Our work
Based on customer requirements the given excited multiphase synchronous machine model has been created and parametrized. Taking care of the tuning for the excitation current PI controller was taken over by the model-based Software Development team of WiredWhite as well. For the modelling of power electronics, multiple options such as Simscape, SimPowerSystems and Plecs has been considered and closely investigated.
In this model WiredWhite team has examined modelling of every single component such as the sub-model of the alternator and the sub-model of the excitation current control, as well as the functional principle of the vehicle power network while running simulations of automotive-typical test cases or driving cycle.
Finally, the model and the control loop have been verified by comparison of simulation results with the measurement results on a test bench.
Results
The typical use case of starting the engine (mimicked by a DC- electric machine) and impact of low voltage generator on vehicle power network and the voltage stability. Our team has modelled a detailed speed profile of the real drivetrain and captured the excitation and load currents and actual voltages, as well as the generator usage. With the laboratory experiments the team was able to verify the quality of the developed model.
Conclusion
This is just one example of a model-based software development project. Our team can provide you a tailor-made decision in the software development for automotive applications.

Hardware development project: electric machine design of a claw-pole alternator.
Task
Create an electric machine design of a claw-pole alternator with a delta-connected six-phase stator winding, rotor winding with the current control and two passive rectifiers.
Our work
The model had to be co-simulated with the model of the power electronics.
Relatively large nominal and maximum speed of the application makes the FEM simulation task more complicated and requires consideration and subsequent investigation of the proximity and skin effects in the stator winding of the machine.
The rotor design considers magnets between-claws, to compensate the leakage flux of the claws and for the enhancing of the main flux of the stator winding.
Results
Based on the created 3D FEM co-model, the behaviour of the automotive six-phase claw-pole alternator and power electronics in the vehicle power network has been investigated. In addition to the FEA, Matlab Simulink models of power electronics, electrical machine and other power network components have been parametrized to provide a detailed analysis of a vehicle power network.
Conclusion
With regards to e-machines, beside the electromagnetic design our team can also support you with insulation system design, mechanical strength analysis and calculation, thermal modelling and cooling system design.
