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.

Abstract: An ignition coil for an ignition system of an internal combustion engine includes a primary winding connected, by an electrical connection, to a generator, and a secondary winding connected to a spark plug and including a plurality of turns of capillary wire covered with an insulating layer and wound on an electrically insulating support. The support includes a receiving seat in which there is inserted a terminal to which an end portion of the capillary wire is anchored. A connector includes an elastic clip contact element that is fitted on the terminal and is provided with a cutting element to cut the insulating layer of the capillary wire. A stop device prevents the elastic clip contact element from closing beyond a determined amount or entity. An abutment body abuts on the terminal to establish the electrical connection between the capillary wire and the terminal.
