Layout techniques for reduction of common mode current in static converters

The radiation is, for the most part, generated by common-mode currents. This paper shows that action on layout can reduce common-mode currents effectively. Cost-effective, the common-mode current control enables the radiation level knowledge at the conception of a device. This is an important gain of time. Four boost structures are studied in order to validate first, experimentally and second by modelling, reduction common-mode current layouts, supposed effective. The simulated models are based on the partial equivalent element circuit (PEEC) method. We show also the impact of these layout techniques on radiated perturbations
