Abstract: A power supply system includes a power supply circuit, a sensor of the current flowing through a terminal of the power supply circuit and a protection circuit. The protection circuit includes a differentiator adapted to measure a slope of a current measurement signal and comprises a driving stage.

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 connected in series to the bias circuit and connected between the bias circuit and the reference voltage.

Abstract: A method of detecting the breakdown voltage between the electrodes of a spark plug connected to an ignition coil for a cylinder ignition system, in an internal combustion engine, comprises a detection of an opening of the switch (105) on the primary winding (102) and a detection of a voltage on that primary winding (102), with the generation of a first signal (V1) representative of the voltage trend following the opening of the switch (105).
The first signal (V1) is then integrated and, following an identification of a breakdown at the ends of the spark plug (106), a breakdown voltage value is determined as a function of the value of the integrated signal at the time of the breakdown.

Abstract: A method for protecting an on-board charging device includes the steps of detecting the phase and neutral voltages coming from the grid, detecting a current signal representing a compensation current generated by a compensation circuit, combining the phase voltages together so as to obtain a homopolar voltage signal, squaring the current signal and the homopolar voltage signal so as to obtain a first square current wave and a second square voltage wave, combining the first and second square waves together so as to generate an output signal having a first logic level when the first and second square waves are in phase and a second logic level when the first and second square waves are out of phase, generating a voltage increasing in proportion to the duration of each section of the output signal having the first value, comparing the voltage value with a limit value and generating an alarm signal when the voltage level exceeds the limit value.

Abstract: A drive system for a hybrid or electric vehicle includes an electrical energy source; an electric machine, a switching device linked to the electric machine and selectively switchable between a first configuration, and a second configuration, an adjusting device linked to the electric machine and configured to vary its operating parameters, and a control unit. The first electrical configuration includes a first number of conductors in series by phase supplying a first driving torque with a first knee speed and a first no-load operation speed. The second electrical configuration includes a second number of conductors in series by phase supplying a second driving torque, lower than the first driving torque, and a second knee speed higher than the first knee speed. A ratio between the first no-load operation speed and the second knee speed is between 0.7 and 1.3.

Abstract: An electronic device for controlling an ignition coil of an internal combustion engine includes a high voltage switch, a driving unit and a control unit. The driving unit controls the closure of the switch during charging energy in the primary winding and the opening of the switch during transferring energy from the primary winding to a secondary winding. A current measuring circuit is connected in series to a second terminal of the secondary winding to detect current generated on the secondary winding during the charging step and generate a signal representative of the detected current. The control unit receives the signal representative of the current detected by the measuring circuit, compares a relevant value of such signal with a predefined first reference value and activates a mode for detecting a soiling of the spark plug when the relevant value of the signal exceeds said predefined first reference value.
