Electromagnetic compatibility of power systems – E-CEM

One way to significantly reduce carbon emissions in transport is to consider the development of hybrid and electric vehicles.
Thus, the use of power converters will rapidly increase in modern vehicles.
In order that the introduction of power converters in transport vehicles be done in harmony with the low-level systems as well as constraints related to human exposure to electromagnetic fields, it has become fundamental to anticipate the behaviour of EMC in power systems at a very early design stage.

As such, this project is a continuation of SP4 program O2M and therefore proposes to continue the development of tools to take into account EMC in static energy convertors. For memory the SP4 O2M has treated the problem of active power component description in time and frequency domains, the near-field coupling between electronic components and taking into account the effect of temperature. The result is the ability to obtain a reliable model for a power module.
These models will be completed by those of harnesses and of motors / actuators. Also a big effort will be made to the propagation phenomena and the development of optimization tools.
The goal now is to go into modelling a subsystem that is to say a system composed only of the power module, a beam and an actuator / motor. This model will allow the search for optimum configuration.
The proposed methods must be adaptable to rapid modelling required during the pre-sizing or simulations more time-consuming giving access to quantitative results. We will study aspects including system modelling and global optimization.
