Abstract: A combination of a main carrier and a printed circuit board. Light and heavy electrical and/or electronic components are fixed on the printed circuit board, wherein at least one heavy component is mechanically fixedly connected to the main carrier and electrically conductively connected to conductor tracks of a first section of the printed circuit board. The first section of the printed circuit board is electrically conductively connected to a second section of the printed circuit board and decoupled from the second section of the printed circuit board with regard to mechanical vibrations by means of a decoupling device. The decoupling device may be, for example, a flexible section or a recess formed in said printed circuit board.

Abstract: A method for measuring the insulation resistance in an IT network. The IT network has a DC voltage intermediate circuit and at least one self-commutated converter having at least one first and one second power switch. The IT network also includes a measuring arrangement for measuring the intermediate circuit voltage relative to ground potential comprising a voltage divider and two assigned potential measuring devices. The method has an offline and an online measurement, wherein, during the offline measurement, all of one of the first and second power switches are closed and the potentials Up and Um, respectively, and also the intermediate circuit voltage are measured and the insulation resistance Rf is determined therefrom. During the online measurement, the two potentials Up and Um are measured and the temporal profile of the measurements is compared with the offline measurement.
