Abstract

An energy supply network has an n-phase electrical machine where n≧1 and a controllable first energy reservoir which serves to control and supply electrical energy to the electrical machine. The first energy reservoir has n parallel energy supply branches that each have at least two energy reservoir modules, connected in series, that each encompass at least one electrical energy reservoir cell having an associated controllable coupling unit and are connected on the one hand to a reference bus, and on the other hand to a respective phase of the electrical machine. As a function of control signals, the coupling units either bypass the respectively associated energy reservoir cells or switch the respectively associated energy reservoir cells into the energy supply branch.
