Abstract (en)

[origin: WO0161821A1] The invention relates to a circuit arrangement that is provided with a chain (1) consisting of double layer capacitors (2). Modules (3) are connected in parallel in relation to the double layer capacitors (2). The impedance of said modules is reduced when the voltage above one of the double layer capacitors (2) exceeds a predetermined value. Overvoltages on the double layer capacitors (2) are thus effectively suppressed.
