Abstract
Voltage converter circuits including a first and second branch. The first branch is coupled between a first DC terminal and a second DC terminal and includes a first and second winding around a magnetic core. The first and second winding are coupled to an AC terminal via a common node. The second branch is coupled in parallel to the first branch between the first and second DC terminals and includes a third winding around the magnetic core. The third winding is coupled to the AC terminal such that the first and second branches convert a first voltage into a second voltage. The first, second and third windings are configured to cause magnetic flux generated by a differential mode (DM) component of a first current in the first branch and magnetic flux generated by the DM component of a second current in the second branch to enhance with each other.
