Abstract
The protection device for providing protection against short-circuits upstream from an electrical power supply module having an inlet filter with at least one capacitor and an inductor and having a converter with components associated with a plurality of freewheel diodes includes at least one auxiliary winding and a dissipator element associated with the inlet filter, thereby making it possible to provide an inlet filter of small size without over dimensioning the freewheel diodes.
