MODULAR MATRIX AC/AC MULTIPOINT CONVERTER HAVING HIGHER-FREQUENCY TRANSFORMERS

摘要

The invention relates to a converter arrangement (1) for converting an alternating input voltage having an input frequency into an alternating output voltage having an output frequency. The converter arrangement (1) comprises a direct converter (9) on the input side having a plurality of input terminals (15) and input-side converter units (17), transformers (11), the number of which matches the number of input terminals (15), and a direct converter (13) on the output side having output-side converter units (21), and a number of output terminals (19), which number matches the number of input terminals (15). Each transformer (11) is connected on the primary side to each input terminal (15) via one each input-side converter unit (17), and is connected on the secondary side to each output terminal (19) via one each output-side converter unit (21).
