1. An electronic device for monitoring an electrical energy converter, the electrical energy converter being adapted to convert an input voltage into an output voltage and comprising a first and a second input terminals adapted to receive the input voltage, at least two output terminals adapted to deliver the output voltage, a first filter branch connected between the input terminals, a second filter branch connected in parallel with the first filter branch, at least two switching branches connected in parallel with the second filter branch, each of the filter branches including a capacitor, each of the switching branches including two switching half-branches connected in series and in an intermediate point, the intermediate point of each switching branch then forming a respective output terminal, each half-branch including at least one switch,
wherein the monitoring device comprises a detection impedance configured for being connected between the first and the second filter branches, and a detection module configured for comparing a voltage across the detection impedance with a predefined voltage threshold, then for generating a detection signal as soon as the voltage across the detection impedance is greater than the predefined voltage threshold, and
wherein a first terminal of the detection module is coupled to a common node of a first leg of the detection impedance and the first filter branch and a second terminal of the detection module is coupled to a common node of a second leg of the detection impedance and the second filter branch.
