Problems solved by technology
[0012] However, shields are not feasible in all cases, or are usually only integratable at substantial additional cost
Furthermore, the shielding leads to possible thermal fuse degradation due to the need for both the shielding layer and at least one additional insulating layer
[0013] Depending on the application (regarding voltage and current), filtering components can be quite expensive, bulky and bulky

Embodiment Construction
[0046] In the following description, the same reference numerals are used for identical and identically acting components.
[0047] figure 1 A schematic diagram of an arrangement comprising resistors to be switched according to the prior art is shown. Here, the resistors to be switched are shown symbolically by resistors R1 to R4. In principle, however, only one (continuous) resistor is involved here. In this respect, the schematically shown resistors R1 to R4 can also be interpreted as resistor parts of a resistor (that is to say, individual parts of a series connection of resistors). Alternatively, however, resistors (for example four) that are actually structurally delimited from each other can also be included here. The resistors R1 to R4 are arranged close to the case 10 for the purpose of heat dissipation (cooling).
[0048] figure 1 The shown capacitors C1 to C5 correspond to a symbolic illustration of the capacitance of the resistors, which is produced by the arra...

The invention relates to an assembly, comprising a heat-emitting resistor (R1 to R4), a control apparatus for switching the resistor (R1 to R4) and an, in particular earthed, component, which is at apotential without direct reference to a drive voltage, in particular a housing or chassis component (10), wherein the resistor (R1 to R4) is arranged in spatial proximity to the component, in particular the housing (10), and has a first (R1, R2) and a second (R3, R4) resistor element, which are connected in series with one another, wherein the control apparatus comprises at least one switching apparatus (M1) for switching the heat-emitting resistor, wherein the first resistor element (R1, R2), the switching apparatus (M1) and the second resistor element (R3, R4) are connected in series in thementioned order and therefore form a series circuit, wherein the first resistor element (R1, R2) and the component form a first capacitance element and the second resistor (R3, R4)and the component form a second capacitance element, wherein the capacitance elements are formed in such a way that, during switching of the resistor, a current flowing in the first capacitance element is at least partlyabsorbed by the second capacitance element or vice versa.
Description
technical field [0001] The invention relates to an arrangement according to claim 1 , comprising a heating resistor, a control device for switching the resistor and a power supply at a potential not directly referenced to the drive voltage (in particular grounded or at a level similar to ground). reference potential) components, in particular housing and / or chassis components, wherein resistors are arranged spatially adjacent to said components, in particular housing and / or chassis components, and the invention relates to a device according to claim 10 corresponding control methods. Background technique [0002] figure 1 The prior art is shown and resistors are shown, which are located near the housing and are symbolically shown as resistors R1 to R4. The resistor is cooled for the purpose of dissipating heat to the case.
