Converter a subject matter a unipolar or bipolar has three windings magnetically pairs.

摘要

The converter has three windings (Ls1, Ls2, Lp) rolled around a magnetic core, where ends of the winding (Ls1, Ls2) are connected to a positive potential (V-p) and a negative potential (V-m) by diodes (D1, D2), respectively. An end of the winding (Lp) is connected at a mid point of a branch connecting two potentials, where the part of branch has a switch forming unit (Q1) and diode (D3). Another end of the winding (Lp) is connected to an output terminal (SP). A number of turns in the winding (Lp) is greater than the number of turns in the windings (Ls1, Ls2). An independent claim is also included for a method for operating the chopper converter.
