Embodiment Construction

[0061] figure 1A typical electrical device 2 for controlling two electric motors 21 , 22 is shown. In order to achieve independent control of the electric motors 21 , 22 with respect to their directions of rotation D1 , D2 and / or rotational speed, two separate H-bridge arrangements 2 - 1 , 2 - 2 are provided in known solutions.

[0062] Here, the first electric motor 21 is arranged in the first bridge branch 2 - 10 of the first H-bridge arrangement 2 - 1 such that it is connected to the first half bridge 23 via the first motor contact 211 and connected to the second half-bridge 24 via the second motor contact 212 . The first half bridge 2 - 1 comprises a first switching element 231 and a second switching element 232 , wherein the first motor contact 211 is connected to an electrical path between the first switching element 231 and the second switching element 232 . Accordingly, the second half-bridge 24 comprises a third switching element 241 and a fourth switching element 2...
