In low power applications, single-stage AC/DC converters are a good option to meet low frequency harmonic regulations because reduced cost and complexity can be obtained in comparison with the two stages approach. "The Series Inductance Interval (SII)" gives name to a new family of single-stage PFC converters focused on three main aspects: a storage capacitor voltage below the peak value of line voltage, low variation of this voltage with fine and load changes, and input current harmonics lower than the EN 61000-3-2 Class D limits for the whole load power range. Universal line voltage operation, efficiency and tight output voltage regulation have also been taken into account. This paper present the principle of operation of the SII converters besides the first experimental results.
