Abstract: A power supply system includes a power feeding system for transforming an AC medium-voltage power signal from a medium-voltage grid into a low-voltage power signal for feeding an electricity consumer site. The power supply system further includes a low-voltage multiphase converter for transforming a low-voltage signal into a low-voltage multiphase signal. The multiphase converter is arranged antiparallel to the power feeding system, and an LV/MV multiphase transformer for transforming the low-voltage multiphase signal into an output-signal that is conformant to the AC medium-voltage power signal.
