Abstract
Electrical power extraction from renewable energy sources such as photovoltaics (PV), wind farms, and some others, have their own technical challenges. It is necessary to perform the power processing tasks according to the nature of the power supply and, at the same time, it is required to be compliant with technical regulations and particular needs of final users. These tasks are achieved with the development of power electronics converters and suitable control systems.
Modular multilevel converters (MMCs) have been during the last years, and will continue to be in the near future, a trending research topic. To better process the electrical power, MMCs can be used where two or three level power converters are used today. This is essentially due to multiple advantages, such as, (i) inherent fault tolerance or some times called redundancy, (ii) application in medium and high power levels, (iii) high scalability: in function of the number of power modules, (iv) better quality of output power, and (v) comparatively low switching frequency.
