Dual line active automatic transfer switch

A dual line automatic transfer switch (ATS), comprising:

• first and second inputs;
• a first switch structure;
• a second switch structure;
• a plurality of power supply units (PSUs) configured in an N+1 architecture;
• and
• a third switch structure connected to at least one of the first and second switch structures, wherein the third switch structure is operable to direct power from the at least one of the first and second switch structures to the plurality of PSUs in a load balancing operation, wherein:
• the first and second switch structures are connected between the first and second inputs and the plurality of PSUs,
• the first switch structure is operable between a first position connecting the first input to a first PSU and a second position connecting the second input to the first PSU,
• the second switch structure is operable between a third position connecting the first input to a second PSU and a fourth position connecting the second input to the second PSU, and
• the first and second switch structures are configured to provide power, when each of the first and second inputs is charged, from each of the first and second inputs to at least one of the first PSU and the second PSU.
