Improving EMC behavior and energy efficiency of Boost converter with power switches having low switching frequency and high dv/dt

Abstract : For reasons of weight, volume and life duration of the battery and standard EMC compliance, transportation embedded systems must present high energy efficiency and comply with international standards of Differential Mode (DM) and of Common Mode (CM). The present paper deals with a boost converter designed to this purpose. Its particularities are to present low switching frequency, high dv/dt, associated with specific passive filters including inductors manufactured with planar thin sheets of copper having low values of inductance and very small resistances. Theoretical analyses and numerical simulations on SABER simulator are carried out to underline the high improvement of DM behavior, and how it can be taken advantage from the inductor parasitic elements to reduce CM perturbations as well. Experimentations tests confirm these benefits and validate the conception considerations.
