Electric generator

An aircraft electrical system comprising:

• a combustion engine;
• and
• an electric generator assembly comprising a main generator comprising a main rotor and a main stator, the main generator rotor driven directly or indirectly by the combustion engine, the main stator comprising a first three-phase winding and a second three-phase winding, the first and second three-phase windings are arranged in parallel, have separate neutral points, and are each configured to have a voltage induced therein by the main rotor, the first three-phase winding defining a phase shift from the second three-phase winding of equal to or approximately equal to 30 degrees,
• the main generator further comprises a first main generator rectifier configured to convert a three-phase AC voltage from the first three-phase winding into a DC voltage and a second main generator rectifier configured to convert a three-phase AC voltage from the second three-phase winding into a DC voltage, the first and second main generator rectifiers each having a first terminal and a second terminal,
• the main generator also comprises a single main generator interphase transformer having a first branch electrically coupled with the first terminal of the first main generator rectifier and a second branch electrically coupled with the first terminal of the second main generator rectifier, the second terminal of the first main generator rectifier and the second terminal of the second main generator rectifier are not electrically coupled with an interphase transformer, and
• wherein the first and second three-phase windings are paralleled through the single interphase transformer.
