| 摘要 |
The invention concerns a DC-DC power converter, suitable for being powered by a primary voltage source and for powering an electronic control system of a three-phase inverter, said three-phase inverter being configured to control a fan of an aircraft ventilation system. The DC-DC converter is characterised in that it comprises a transformer (16), a primary circuit (12) comprising two loops forming a push-pull configuration, at least one secondary circuit (14) comprising a secondary winding (LS), suitable for supplying, to the inverter, an output voltage equal to double the peak voltage at the terminals of the secondary winding (LS), and, to a branch of the circuit suitable for supplying the inverter, 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 to zero voltage. |
