| 摘要 |
The invention relates to a symmetry device (45), especially for one or more switched-mode power supply units (1), said unit being operated in the switching mode in a primary manner. This unit is comprised of at least one primary module (2, 3) which is operated in the switching mode by a control device (27), and is comprised of at least one secondary module (4). The power is transmitted between the primary module (2, 3) and the secondary module (4) via one or more transformers (5) each comprising at least one primary winding (6, 7) and at least one secondary winding (8). A common symmetry device (45), especially a transmission device (46), for equalizing power between the primary windings (6, 7) is arranged in the supply circuit for each primary winding (6, 7) of the transformer (5) or for each of several transformers (5). |
