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 first secondary side (10), wherein the primary side (8) is electrically isolated from the first 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 a second secondary side (9) is configured to be connected to an external output unit (13) wherein that the first secondary side (10) is configured to be connected to an external input source (14), wherein the first and second 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) whereby an isolated current-to-current transformation is able to be produced between the external input source (14) that is capable of being connected/coupled to the the another secondary side (10) and the one (9) of the secondary sides that is capable of being connected/coupled to the external output unit (13), thereby enabling an input current (15) to be duplicated on an output side in the form of an output current (16) which is configured to be connected to the external output unit (13), whereby an isolated current-to-current transformation is able to be produced between the external input source that is capable of being connected/coupled to the external input unit and the external output unit that is capable of being connected/coupled to a load unit/circuit, thereby enabling an input current to be duplicated on an output side in the form of an output current which is configured to be connected to an external power source.
