Embodiment Construction
[0033] figure 1 A capacitor arrangement 1 for a (direct current) intermediate circuit of a pulse converter in a drive train of an electric vehicle is shown.
[0034] The capacitor arrangement 1 comprises two capacitor plate stacks 2 and 3 . Capacitor plate stacks 2 and 3 are each a film capacitor, which is conventional per se. Each capacitor plate stack 2 and 3 is formed accordingly from a roll of metallized plastic film, wherein this roll is on both end sides (in accordance with figure 1 are located above and below in the illustration) are metallized to form the connecting surface (hereinafter referred to as Schoob surface (Schoob-Flaechen) 4 ).
[0035] The capacitor arrangement 1 also comprises two busbars for connection to the intermediate circuit, namely a busbar 5 on the high potential side (positive busbar) and a busbar 6 on the low potential side (negative busbar). Each busbar 5 , 6 is formed in each case from a stamped part made of tin-plated copper sheet.
