Beschreibung
Zusammenfassung:	The invention relates to an electric DC-DC converter suitable for being supplied with power by a primary voltage source and for supplying control electronics of a three-phase inverter with power, said three-phase inverter being configured to control a fan of a ventilation system of an aircraft. The DC-DC converter is characterised in that it comprises a transformer (16), a primary circuit (12) comprising two loops forming a symmetrical assembly, at least one secondary circuit (14) comprising a secondary winding (LS), suitable for supplying, firstly, the inverter with an output voltage equal to twice the peak voltage at the terminals of the secondary winding (LS) and, secondly, a branch of the circuit suitable for supplying the inverter with an output voltage equal to the opposite of the peak voltage at the terminals of the secondary winding (LS), and in that the controllable transistors (M1, M2) are suitable for each being switched at zero voltage.
