Compatibility Electromagnetic (EMC) in the design process of the power converters
This talk begins with a presentation of the electromagnetic compatibility (EMC) standards to be respected in order to allow the marketing the electronic and power electronic products. In order to comply with these standards, while reducing costs and development times, it is necessary to take EMC constraints into account from the earliest phases of system design. After a presentation of the various physical phenomena allowing the analysis of electromagnetic interference (EMI) issues, we will present an example of design approach based in simulations, in the time and frequency domain, of an adjustable speed driver of AC motor (electric drives). High frequency characterization and modelling methods of active and passive components are presented. Thus, the obtained model is used for the design by simulation of the considered system taking into account the EMC constraints. The identification of EMI sources and propagation paths of disturbances will make it possible to determine the spectra of conducted emissions in order to verify the compliance with EMC standards. Finally, various solutions to reduce conducted emissions of electric drivers are presented. We will detail the design and optimization method of the EMI filters for power converters.
