Nowadays, the Modular Multilevel Converter represents an important solution for grid applications, as it can easily extend the output voltage range, as required for instance in high voltage applications. The present paper studies the generalization of such a converter to a resonant version, not already used in high power applications, analyzing...

The Modular Multilevel Converter (MMC) concept is a modern energy conversion structure that stands out for a number of interesting features that opens wide application chances in Power Systems, for example for efficient grid integration of renewable sources. In these high-voltage, high-power application fields, a high efficiency is mandatory....

One of the most important innovation expectation in railway electrical equipment is the replacement of the on-board transformer with a high power converter. Since the transformer operates at line-frequency (i.e., 50 Hz or 16 2/3 Hz), it represents a critical component from weight point of view and, moreover, it is characterized by quite poor...
