Embodiment Construction
[0028] In the following drawings, the same technical features of different embodiments also use the same reference numerals.
[0029] refer to Figure 1 to Figure 3 , schematically visualizes the method according to the invention for operating at least one electrical component 11 , wherein the component 11 may in particular be a drive component 11 of a vehicle 10 . The drive unit is powered by a battery 12 , in particular a high-voltage battery 12 , and is operated thereby.
[0030]The battery 12 can be connected to the component 11 via an intermediate circuit 13 , wherein the intermediate circuit 13 has at least one intermediate circuit capacitor 14 . The intermediate circuit capacitance of intermediate circuit capacitor 14 is used here to avoid harmful current fluctuations. However, when the battery 12 is coupled to the component 11, a very large current may be generated, which must be limited to a non-emergency range in order to avoid emergency operating conditions.
