Claim 10:
11. A power supply system comprising:
a first segregated power section comprising a first main switch board and at least one of a first power generator configured to generate electrical power to the first main switch board and a first power consumer drawing power from the first main switch board;
a second segregated power section comprising a second main switch board and at least one of a second power generator configured to generate electrical power to the second main switch board and a second power consumer drawing power from the second main switch board;
a bus-tie connecting the first main switch board and the second main switch board;
a first segregated directly powered thruster redundancy group coupled to and receiving AC power from the first main switch board through a first AC interconnection, wherein the first segregated directly powered thruster redundancy group comprises a first thruster drive connected to the first main switch board, a first AC/DC converter, and a first DC/DC type breaker;
a second segregated directly powered thruster redundancy group coupled to and receiving AC power from the second main switch board through a second AC interconnection, wherein the second segregated directly powered thruster redundancy group comprises a second thruster drive connected to the second main switch board, a second AC/DC converter, and a second DC/DC type breaker;
an indirectly powered thruster redundancy group comprising a thruster drive, a thruster, and an energy storage,
wherein the indirectly powered thruster redundancy group is connected via a first DC interconnection to the first segregated directly powered thruster redundancy group and comprises a third DC/DC type breaker for at least one of control and protection of the first DC interconnection,
wherein the indirectly powered thruster redundancy group is connected via a second DC interconnection to the second segregated directly powered thruster redundancy group and comprises a fourth DC/DC type breaker for at least one of control and protection of the second DC interconnection, and
wherein the indirectly powered thruster redundancy group is powered only through at least one DC interconnection of the first and second DC interconnections from at least one of the first and second segregated directly powered thruster redundancy groups.
