The invention relates to an isolated DC/DC converter (1) comprising: —a first branch (A) comprising series-connected switches (MA1, MA2), the first branch (A) being connected to the input of the converter; —a second branch (B) comprising series-connected switches (MB1, MB2); —an inductance (L2) connected between the midpoints of the first and the second branch (B); —a capacitor connected across the end terminals of the second branch (B); —a third branch (C) comprising a magnetic component and connected to the midpoint of the second branch (B); wherein a series of opening and shutting actions of the switches (MA 1, MA2, MB1, MB2) converts an input voltage (Ue) into an output voltage (Uout) by means of the magnetic component.
