CONVERTER WITH SHARED CURRENT PATH AND ISOLATION BARRIER

摘要

A converter with at least one or more transformers having at least one primary side magnetically coupled to at least one secondary side, the primary side being electrically isolated from the secondary side, wherein a first transformer has first and second sets of coils and a second transformer has third and fourth sets of coils. The first set of coils is connected in series to the third set of coils, wherein one of the secondary sides is connectable to an external output unit, wherein another secondary side is connectable to an external input source, wherein the two secondary sides are electrically isolated from each other, wherein the primary side is adapted to drive the transformers that are connectable to an external power source. The converter uses a shared current path and an isolated current-to-current transfer between the input and output sides to replicate the input current to an output current.

1. A converter (1) comprising at least one or more transformers (2, 5) having at least one primary side (8) magnetically coupled to at least one secondary side (10), wherein the primary side (8) is electrically isolated from the secondary side (10) by an isolation barrier (11), wherein a first transformer (2) comprises a first set of coils (3) and a second set of coils (4) and a second transformer (5) comprises a third set of coils (6) and a fourth set of coils (7) where the first set of coils (3) is connected in series to the third set of coils (6), wherein one (9) of the secondary sides is configured to be connected to an external output unit (13) wherein that another secondary side (10) is configured to be connected to an external input source (14), wherein the two secondary sides (9, 10) are electrically isolated from each other by a second isolation barrier (12), wherein the primary side (8) comprises means configured to drive the transformers (2, 5) which is configured to be connected to an external power source (17).
