Title:
TRANSFORMERLESS MODULAR CYCLOCONVERTER COMPRISING DISTRIBUTED
Document Type and Number:
WIPO Patent Application WO/2011/120679
Kind Code:
A3
Abstract:
The invention relates to a transformerless cycloconverter for connecting a first three-conductor grid (50), in particular a three-phase grid, to a second three-conductor grid (51), in particular a three-phase grid, by means of bridge modules comprising electronic semiconductor circuits (5, 6, 7, 8), having the following characteristics: a) a first bridge module (1) or a first series circuit (52) of bridge modules (1) is connected to a first conductor (500) of the first power supply grid (50) on one side and to a first conductor (510) of the second power supply grid (51) on the other side, b) a second bridge module (1) or a second series circuit (53) of bridge modules (1) is connected to a second conductor (501) of the first power supply grid (50) on one side and to the first conductor (510) of the second power supply grid (50) on the other side, c) a third bridge module (1) or a third series circuit (54) of bridge modules (1) is connected to the second conductor (501) of the first power supply grid (50) on one side and to a second conductor (511) of the second power supply grid (51) on the other side, d) a fourth bridge module (1) or a fourth series circuit (55) of bridge modules (1) is connected to a third conductor (502) of the first power supply grid (50) on one side and to the second conductor (511) of the second power supply grid (51) on the other side, e) a fifth bridge module (1) or a fifth series circuit (56) of bridge modules (1) is connected to the third conductor (502) of the first power supply grid (50) on one side and to a third conductor (512) of the second power supply grid (51) on the other side, and a sixth bridge module (1) or a sixth series circuit (57) of bridge modules (1) is connected to the first conductor (500) of the first power supply grid (50) on one side and to the third conductor (512) of the second power supply grid (51) on the other side.
