Abstract (en)
[origin: WO2022223756A1] The present invention proposes a converter comprising at least one switching arm (16), comprising: a ground terminal (17), a supply terminal (18), a first and a second power component (Q1, Q2) and a phase terminal (19). The voltage converter (15) furthermore comprises a protection device (22) for protecting the switching arm (16), configured to detect a fault mode in which the first and the second power component (Q1, Q2) are in the on state, the protection device (22) comprising a measuring module (23) designed to emit an offset voltage based on a measured voltage of the switching arm and on a reference voltage, and a detection module (24) designed to emit an integral signal corresponding to the integral of the offset voltage.
