<p>The circuit has a number of switching devices (S11-S24), each connected in series with a respective resistance (R11-R24), with an electronic evaluation stage (AE) determining the switch condition of each switching device via a current measurement. The switching devices are divided into two groups (1,2), with the input (e1,e2) of each group coupled to the electronic evaluation stage via a respective diode (D1,D2) and coupled to the output (a2,a1) of the other switching device group. The inputs and outputs of both switching device groups are coupled in alternation to the DC supply terminals at given time intervals via the electronic evaluation stage.</p> |
