Summary:An electrical power supply system (1) for an aircraft (28), comprises a plurality of generators (2, 6), each being couplable to and rotatable by an aircraft engine (4, 8), each generator (2, 6) comprising at least four AC phases (2a, 2b, 2c, 2d, 6a, 6b, 6c, 6d), and a plurality of electrical conversion units (10, 12, 14, 16), each having a plurality of inputs (10a, 10b, 12a, 12b, 14a, 14b, 16a, 16b) and at least one output (10x, 12x, 14x, 16x), wherein the inputs (10a, 10b, 12a, 12b, 14a, 14b, 16a, 16b) of each individual electrical conversion unit (10, 12, 14, 16) are connected to a plurality of phases (2a, 2b, 2c, 2d, 6a, 6b, 6c, 6d) of at least two of the plurality of generators (2, 6). The electrical conversion units (10, 12, 14, 16) each comprise a rectification and conversion device (18) for providing an output voltage having a predeterminable frequency and voltage level at the output.
