Abstract (en)
[origin: WO2021229190A1] The invention relates to a three-phase autotransformer (8) comprising three groups of outputs and three inputs (E1, E2, E3) each connected to each of the outputs of one respective group of outputs via windings, the windings being configured so that, when each input applies a respective input voltage, the three input voltages having the same input amplitude, being phase shifted by 120° with respect to each other and defining a neutral point: - for each group of outputs, a main output voltage, measured between a main output of said output group and the neutral point, has an amplitude higher than the input amplitude; and - the output voltages of the autotransformer belong to the same Reuleaux polygon, each output voltage being associated with one respective output and being equal to a voltage between said output and the neutral point.
