| 摘要 |
The invention relates to an integrated magnetic component (103) for a switched mode power converter, which includes a transformer with two transformer core elements (E2, E3) and at least one choke core element (E1, E4). Each core element (E1, E2, E3, E4) comprises two outer legs (120a, 120b) and a flange (122) which connects the outer legs (120a, 120b) to form U-like core elements. Each choke core element (E1, E4) abuts a flange (122) of one of the transformer core elements (E2, E3). The integrated magnetic component (103) includes a first choke winding (123) arranged on a leg (121.1) of a choke core element (E1) and a second choke winding (124) arranged on another leg (121.4) of a choke core element (E4), where one of a primary (P1, P2) or a secondary winding (S1, S2) of the transformer is connected between the choke windings (123, 124) and where all windings (P1, P2, S1, S2, 123, 124) are interconnected to reduce core losses by flux compensation in order to increase power density. |
