Abstract: A method for converting an input voltage (Vin) of a converter (1) into an output voltage (Vout), the circuit comprising a first bridge arm consisting of two switches (A) and (B), a second bridge arm consisting of two switches (C) and (D), connected in parallel, a primary coil coupled to a secondary coil, and connected by a center point pole (PAB) of the first bridge arm, and by another center point pole (PCD) of the second bridge arm; the circuit further comprising a capacitor in parallel between the respective terminals of each of the switches (A, B, C, D); a third bridge arm formed by two switches (E) and (F), connected in series; each of the switches (A, B, C, D, E, F) being associated with a diode at the terminals of said switch; an injection inductance (Linj) connected to the center point (PAB) of the first bridge arm, and to the center point (PEF) of the third bridge arm; a monitoring-control unit configured to control the switches to turn them ON or OFF, according to a control cycle configured to ensure soft switching between ON and OFF.
