Abstract: A power supply system includes one or more solid state transformers (SST), one or more first stage DC-DC converters and one or more second stage DC-DC converters. The one or more solid state transformers (SST) are configured to convert any medium-voltage Alternating Current (MVAC) input or medium-voltage Direct Current (MVDC) input to a first low-voltage Direct-Current (LVDC) output. The one or more first stage DC-DC converters are configured to convert the first low-voltage DC output to a second LVDC output. The one or more second stage DC-DC converters are configured to convert the second LVDC output to a third LVDC output. The third LVDC output is used to supply power to one or more servers in a data centre ICT load area.
