摘要 |
The invention relates to a switched-mode power supply arrangement comprising at least two switched-mode-type power supplies (1) that comprise a transformer (2) and that have outputs (Uout) connected in parallel. According to the invention, each parallel-connected switched-mode power supply (1) comprises means (4) for generating in a reference voltage output (Uref) a voltage that is proportional to the pulse duty factor of the secondary voltage of the transformer (2), the reference voltage outputs (Uref) of each switched-mode power supply (1) to be connected in parallel are coupled together, and each parallel-connected switched-mode power supply (1) also comprises means (5, 6) for detecting a current flowing through the reference voltage output (Uref) and for generating a correction voltage (Ucor) that is proportional to this current in order to correct the output voltage (Uout) of the switched-mode power supply.
