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

摘要

A converter arrangement converts an alternating input voltage having an input frequency into an alternating output voltage having an output frequency. The converter arrangement includes a direct converter on an input side having a plurality of input terminals and input-side converter units, transformers, the number of which matches the number of input terminals, and a direct converter on an output side having output-side converter units, and a number of output terminals, which number matches the number of input terminals. Each transformer is connected on the primary side to each input terminal via one each input-side converter unit, and is connected on the secondary side to each output terminal via one each output-side converter unit.
