Direct modular AC converter without transformer with distributed energy storage

摘要

Direct AC converter without transformer for the connection of a first three-line network (50), particularly a three-phase network, to a second three-line network (51), particularly a three-phase network, by means of bridge modules (1 ) with electronic semiconductor switches (5, 6, 7, 8), with the following characteristics: a) a first bridge module (1) or a first series circuit (52) of bridge modules (1) is connected, on the one hand, to a first line (500) of the first power supply network (50) and, on the other hand, to a first line (510) of the second power supply network (51), b) a second bridge module (1) or a second series circuit (53) of bridge modules (1) is connected, on the one hand, to a second line (501) of the first power supply network (50) and, on the other hand, to the first line (510) of the second power supply network (51), c) a third bridge module (1) or a third series circuit (54) of bridge modules (1) is connected, on the one hand, to the second line (501) of the first power supply network (50) and, on the other hand, to a second line (511) of the second power supply network (51), d) a fourth bridge module (1) or a fourth series circuit (55) of bridge modules (1) is connected, on the one hand, to a third line (502) of the first power supply network (50) and, on the other hand, to the second line (511) of the second power supply network (51), e) a fifth bridge module ( 1) or a fifth series circuit (56) of bridge modules (1) is connected, on the one hand, to the third line (502) of the first power supply network (50) and, on the other hand, to a third line (512) of the second power supply network (51), f) a sixth bridge module (1) or a sixth series circuit (57) of bridge modules (1) is connected, on the one hand , to the first line ea (500) of the first power supply network (50) and, on the other hand, to the third line (512) of the second power supply network (51), characterized in that the direct alternating current converter has exactly six bridge modules or series circuits thereof.
