This AC/DC converter is an isolated converter with switch-mode current regulation by means of a controlled switch (5). The controlled switch (5) is protected by a current limiting device (9, 7) obeying a peak current setpoint proportional to the instantaneous voltage from the power supply source (Vin). This allows the quality of the absorbed current to be improved and the risks of interference from the switch-mode power supply to be limited while at the same time satisfying the new demands on avionics power networks.
