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.

Abstract: A method for monitoring an engine cylinder in an internal combustion engine includes, for each engine cycle, detection of the ionisation current generated in the cylinder in a predetermined time interval of a combustion cycle, generation of a signal representing the ionisation current and comparing a maximum value of the signal with a threshold value. Successively, the value of one or more parameters associated with the signal can be changed with respect to an equal number of corresponding reference values when the maximum value of the signal exceeds the threshold value, to reduce the maximum value of the signal in the time interval of a successive combustion cycle. The presence of water in the cylinder can be determined when the maximum value of the signal exceeds the threshold value for a predetermined first number of combustion cycles occurring within a predetermined period of time.

Abstract: A method for estimating the magnet temperature in an electrical machine carried out by means of an electronic computer involves estimating a value of a total magnetic flux of the electrical machine and estimating a value of a first partial flux, representing a magnetic flux due to a reluctance of the electrical machine. The method also involves the steps of calculating a value of a second partial flux as a function of a difference between said value of the total magnetic flux and said value of the first partial flux and determining a value of a magnet temperature as a function of said value of the second partial flux.

Abstract: A method for heating an exhaust pipe in a motor vehicle, including a plurality of spark cycles performed in succession at a preset frequency, wherein each spark cycle includes injecting a-preset fuel quantity into an injection area inside of an exhaust pipe in a motor vehicle and generating at least one spark between the ends of a pair of electrodes located in proximity to the injection area in order to start combustion.
Thus, a value of an ionization current flowing between the ends of the pair of electrodes is detected following the extinction of the spark and this ionization current value is compared with a preset reference value.
Therefore, the presence of combustion in the spark cycle is determined, if the ionization current value is greater than the preset reference value, or the absence of combustion in the spark cycle, if the ionization current value is lower than the preset reference value.-

Abstract: A switching device for an electric motor provided with a plurality of phases includes a fixed body equipped with a plurality of connection portions and at least one moveable body that can be moved with respect to the fixed body between at least a first position, in which the phases are arranged in a first electrical configuration, and a second position, in which the phases are arranged in a second electrical configuration. The second electrical configuration is separate from the first one due to the connection between the phase fractions within each phase and/or due to the reciprocal connection between the phases.

Abstract: It is disclosed an electronic device to control an ignition coil of an internal combustion engine comprising a high-voltage switch, a driving unit, a bias circuit and an integrating circuit. The high-voltage switch is connected in series with a primary winding of a coil. The driving unit is configured to control the closing and opening of the high-voltage switch. The integrating circuit is interposed between the bias circuit and a reference voltage. The integrating circuit comprises an integrating capacitor. The integrating capacitor is configured, in the case wherein a pre-ignition of the comburent-combustible mixture in the combustion chamber during the phase of charging occurs, to pre-charge during the phase of charging energy in the primary winding and it is configured, in the case wherein the pre-ignition of the comburent-combustible mixture does not occur, to maintain the charge state substantially constant during the phase of charging energy.
