Automatic voltage changing device, intended for the application of the input current to one of the terminals of the primary of a transformer, precisely that corresponding to the magnitude of that voltage, essentially characterized by the arrangement, associated with two input terminals to the aforementioned primary, corresponding to two values of the feeder voltage, as well as to the output of an auxiliary secondary, of two inverting circuit devices, the moving part being connected from the first to one of the current input conductors and in the second to a rectifier circuit formed by four semiconductor diodes arranged in a bridge, producing a direct current applied to the coil of an electromagnetic relay, which has a high-capacity polarized capacitor mounted in parallel, resulting in the reversal of the mobile switching part when the applied voltage corresponds to the maximum value, and remaining immobile il the aforementioned inverter system for the lower value of the aforementioned voltage.
