Electrical energy conversion is increasingly used in actualnelectrical systems. Also, the reduction of energy losses during energynconversion has become an important objective. Thus, the electronicnswitch speed has been increased and allowed to reduce losses, but thentechnological implantation of components induces some electromagneticncompatibility problems. This is the reason of the interest of staticnconverter designers in electromagnetic compatibility. The study concernsnthe different risks of static converter malfunctioning due to itsntechnology. Connections between energy sources (receiver andntransmitter) and electronic switches (power unit and control unit) arenoften constituted of printed circuit traces, wires and copper bars. Thisnconnection is not perfect and its parasitic elements can disturb thenstatic converter, even sometimes causing it to malfunction. The proposednstudy remains qualitative and unfolds in two ways. In the first way,nmalfunctioning causes are shown according to the technology. For eachncase, risks are evaluated and design rules outlined. In the second way,nproposed rules are applied to a power static DC/DC converter, allowingnimprovement of the layout for better operating safety
