Inverter arrangement and electric motor arrangement comprising an inverter arrangement

Abstract

Inverter arrangement for supplying two electric motors, comprising a first inverter unit (2) with a first capacitor unit (4) with first and second capacitor terminals (11, 12) and a second inverter unit (3) with a second capacitor unit (7) with first and second capacitor terminals (11, 12), an EMC filter (9) with a first and a second filter terminal (29, 30), wherein the first capacitor terminals (11) are electrically coupled to the first filter terminal (29) and the second capacitor terminals (12) are electrically coupled to the second filter terminal (30), wherein the identical capacitor units (4, 7) arranged parallel to each other and rotated by 180° relative to each other have an identical arrangement of the first and second capacitor terminals (11, 12) in number and position, wherein a distribution busbar (10) is provided for electrical coupling of the capacitor terminals (11, 12) to the filter terminals (29, 30),comprising an arrangement of first and second rail capacitor terminals (19, 24) corresponding to the number and positioning of the capacitor terminals (11, 12), wherein the first rail capacitor terminals (19) are connected to the first capacitor terminals (11) and the second rail capacitor terminals (24) are connected to the second capacitor terminals (12), and a first and a second rail filter terminal (21, 26), wherein the first rail filter terminal (21) is connected to the first filter terminal (29) and the second rail terminal (26) is connected to the second filter terminal (30).
