摘要：

This paper presents the results of experimental activity concerned with the development of a 600-W boost power-factor corrector (PPC) complying with the EMC standards for conducted EMI in the 150-kHz-30-MHz range. In order to accomplish this task, different circuit design and layout solutions are taken into account and their effect on the conducted EMT behavior of the converter is experimentally evaluated. Common-mode and differential-mode switching noise, together with input filters' design and topology and with the printed circuit board layout tin terms of track length and spacing, ground and shielding planes, etc.) are the key aspects which have been considered, In particular, the paper reports the conducted EMI measurements for different filter capacitor placements and values, for different power switch drive circuits, together with several other provisions which have turned out to be decisive in the reduction of the generated EMI.
