Abstract: An electric or hybrid electric-endothermic traction system comprises an electric machine, an inverter, a battery, and a switching device configured to switch between a low-speed configuration, in which the stator windings assume a first electric configuration, and a high-speed configuration, in which the stator windings assume a second electric configuration, wherein the first electric configuration results in a voltage induced by the rotation of the rotor that, on reaching a pre-determined threshold value of the angular velocity of the rotor, exceeds a supply voltage of the battery, whereas the second electric configuration of the stator windings results in a voltage induced by the rotation of the rotor that is lower than the voltage of the battery for any angular velocity within a range of use of the machine. An emergency device is connected to the switching device, control unit and/or inverter.

Abstract: A power factor correction device includes a power supply side which can be connected to an alternating current source, an output side which can be connected to a direct current load, at least a first power inductor electrically connected in series to a first terminal of the power supply side, and a rectifier operatively interposed between the power supply side and the output side. The rectifier includes a diode bridge configured to convert the alternating current from the source into a direct current towards the load, and one or more switches which can be selectively switched between an open configuration and a closed configuration in order to switch the rectifier between a first configuration, in which it interrupts the current flow towards the output side and charges the first inductor, and a second configuration, in which it allows the transfer of current to the load and discharges the first inductor. A second power inductor is electrically connected in series to a second terminal of the power supply side.

Abstract: A method for measuring an earth resistance in a battery charging system, including the steps of injecting a measuring signal in alternating current between a first, neutral node and a second, earth node, detecting a voltage signal representing an electrical potential difference between the first and the second node, processing the voltage signal so as to extract a first signal having a frequency equal to that of the measuring signal and a phase correlated thereto, and calculating an earth resistance value as a function of a ratio between the measuring signal and a reference value of said first signal.
