Abstract
A new AC/AC modular multilevel topology for connecting two three-phase systems is introduced. The operating principle is explained and characteristic waveforms are given. It is shown that the converter system offers superior performance for applications like low-frequency wind turbines. The analytic results are verified by a laboratory setup.
