Title:
DUAL-SWITCH CURRENT CONVERTER
Document Type and Number:
WIPO Patent Application WO/2012/013329
Kind Code:
A3
Abstract:
The invention relates to a current converter of the forward converter type for converting a three-phase primary voltage (U1, U2, U3) into a plurality of secondary voltages (ud1... udn), having a magnetic intermediate circuit that comprises at least three transformer secondary windings (7, 8, 9), wherein the current converter, on the primary side thereof, has at least three transformers (T1, T2, T3), each having two primary windings (1,2; 3,4; 5,6;) which are wound in opposite directions and at least one secondary winding (7, 8, 9), and two electronic switches (S1, S2) are provided, wherein the first switch (S1) in each case controls a primary winding (1, 3, 5) of the three transformers (T1, T2, T3) via a set of diodes (D1. 1... D1.6), and wherein the second switch (S2) in each case controls another primary winding (2, 4, 6) of the three transformers (T1, T2, T3) via a second set of diodes (D2.1... D2.6).
