Abstract
A circuit for the limitation of over-voltages in energy storage modules having a series circuit of energy storage elements connected between a first potential and a second potential includes voltage-limiting elements associated with combinations of the energy storage elements. Where 'M' is the maximum number of directly interconnected energy storage elements of a predetermined combination, wherein for M≧2 a voltage-limiting element is connected in parallel with each combination and a respective voltage-limiting element is connected in parallel with a first energy storage element connected to the first potential and with an nenergy storage element connected to the second potential. For M>2 a respective voltage-limiting element is connected in parallel with each sub-combination of at least two directly interconnected energy storage elements of the combination having an energy storage element connected to the first potential or to the second potential.
