DC voltage converter for bidirectional power transfer from the primary side of the DC voltage converter to the secondary side and vice versa

摘要

The present invention relates to a DC voltage converter (10) for power transfer from a secondary side to a primary side of a DC voltage converter (10), such a DC voltage converter comprising a controlled first switch (1) and a controlled second An active clamp type flyback converter circuit with 2 switches (2) is provided on the primary side, the primary side is inductively connected with the secondary side, in which case the current of the secondary side secondary coil (6) is 1 Switched by a single controlled secondary-side tertiary switch 3 for inductive coupling with the secondary side, the DC voltage converter has a control device 12 , which control device has in parts of the regulation cycle The third switch 3 is conductively connected to the first switch 1 .
