• the multi-winding transformer 1633 allows an input voltage to be applied to the primary coil S1634 in an extremely compact manner by means of different secondary coils S1635, S1636 and S1637 Different output voltages are provided for the preferably different power electronics components 1635, 1636 and 1637. It is understood by a person skilled in the art that the number of three power electronics components 1635, 1636 and 1637 shown in the exemplary embodiment according to FIG. 6 is selected only by way of example and is not restrictive for the invention.
• control line (from 140 to 132 or 133)
