Abstract

The invention relates to a three-phase alternating current, AC, to direct current, DC, power converter, comprising a boost power factor correction, PFC, circuit (2) comprising a low frequency diode-based converter (7) configured for connecting a PFC input of the converter (7) to an AC source (5), and a PFC inductor (10) and a PFC capacitor (11) connected in series together and in parallel to a PFC output of the converter (7), further comprising either a high frequency PFC diode (8) and a high frequency PFC switch (9) connected in parallel to the PFC output of the converter (7) or comprising a plurality of high frequency PFC switches (9) each connected in parallel to one of the diodes of the converter (7), a Cuk converter (3) comprising a first Cuk inductor (12) and a Cuk capacitor (13) connected in series, a second Cuk inductor (15) and a high frequency Cuk diode (14) connected in parallel to the series connection and forming, via a series connection with the second Cuk inductor (15), a Cuk output (16) to which a DC load (6) can be connected, and a transformer (4) having a primary side connected in parallel to the PFC capacitor (11) and a secondary side connected in parallel to the Cuk capacitor (13).
