The increasing use of renewable energy sources, such as wind and solar power, inevitably leads to fluctuations in energy supply. To not overload the energy grid, control mechanisms for balancing these fluctuations are required. This is where multilevel converters come into play, as they control the amount of energy fed to the grid. They are also used when electric energy is transferred to the consumers over long distances, because long-distance power distribution requires energy grids with different line voltages.
