Abstract: It is disclosed an electronic monitoring circuit (4) for detecting a variation in the power or current absorbed by an electronic circuit (2) under test. The circuit comprises an input terminal adapted to receive a pulse-width modulation control signal (S_pwm_ctrl), a resistor (4-3) having a first terminal connected to the input terminal, and a capacitor (4-1) having a first terminal connected to a second terminal of the resistor (4-3). The output terminal is adapted to generate an output signal (S_∆T) as a function of the value of the voltage drop at the ends of the capacitor, said output signal (S_∆T) being representative of a variation (ΔT+, ΔT-) of the pulse width of the pulse-width modulation control signal (S_pwm_ctrl), wherein said variation of the pulse width is a function of the power or current absorbed by the electronic circuit under test.

Abstract: A method for protecting an on-board charging device (100) comprises 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.
