Abstract

A lot of power topologies have been proposed to comply with the IEC-61000-3-2 regulations. One group of solutions involves obtaining an additional output from one of the converter´s magnetic devices. These solutions are very good due to the low harmonic content and from the low cost point of view. Nevertheless these magnetic coupled circuits can modify the converter´s performance. The abnormal operation can be observed as an output voltage ripple higher than expected. This paper deals with the design considerations for low output voltage ripple single-stage-input-current shapers (S²ICS) and explains the abnormalities
