INTERLEAVED CONVERTER

WIPO Patent Application WO/2020/248168

A1

Embodiments of present disclosure relates to voltage converter circuit comprising a first branch and a second branch. The first branch is coupled between a first DC terminal and a second DC terminal and includes a first winding and a second winding around a magnetic core. The first winding and the 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 are configured to convert a first voltage into a second voltage. The first, second and third windings are configured to cause magnetic flux generated by differential mode (DM) component of a first current in the first branch and magnetic flux generated by DM component of a second current in the second branch to enhance with each other.
