The application relates to a charging system, including a number of m chargers each adapted for providing electrical energy to charge an electrical vehicle, whereby m is an integer and m&#x2265;1, a number of n outlet ports each adapted for electrically connecting the electrical vehicle, whereby n is an integer and n&#x2265;2, and a switchable connection matrix device including a number of n outlet port switches each adapted for electrically connecting at least one of the m chargers to one of the n outlet ports and, if m&#x3e;1, a number of m&#x2212;1 charger switches each adapted for electrically connecting two of the m chargers, whereby the switchable connection matrix device is adapted for detecting a short-circuit between at least two outlet ports and/or for generating a fault signal if the short-circuit between at least two outlet ports is detected.

Safety interlock

A semiconductor stack for a converter comprises two series-connected semiconductor switches; two terminals for connecting a cell capacitor, which are connected to one another by the two semiconductor switches; at least one cooling element arranged between the semiconductor switches; a frame, by which the semiconductor switches and the cooling element are fixed to one another and which provides the terminals; and at least two snubber capacitors which are mechanically fixed to the frame and which are connected in parallel, are connected to the terminals and which in each case form a commutation loop with the semiconductor switches.
