Abstract: A converter for converting a medium voltage AC power into a low voltage DC power is provided. The converter includes a line interphase transformer having at least one core, a plurality of coils provided on the at least one core and configured for receiving the medium voltage AC power, and at least one auxiliary winding provided on the at least one core and inductively coupled to the medium voltage AC power by the core. The line interphase transformer is configured for generating a plurality of phase-shifted AC powers from the medium voltage AC power. The converter further includes a rectifier configured for generating a medium voltage DC power from the plurality of phase-shifted AC powers, and a DC/DC converter stage including a switching stage and a converter transformer. The DC/DC converter stage is configured for generating a low voltage DC power from the medium voltage DC power.
