Abstract:
1. A power inverter, comprising: a power module providing an inverter circuit for inverting DC current supplied from a DC power source to AC current; a smoothing capacitor module for smoothing the DC current; a DC bus bar for supplying the DC current to said power module; an AC bus bar for supplying the AC current to a motor; a housing for installing said power module and said smoothing capacitor module; and a terminal box which is located facing a first side wall formed at said housing; wherein said first side wall provides a first hole in which said DC bus bar penetrates, and a second hole in which said AC bus bar penetrates; wherein a first wall of said terminal box facing the first side wall provides a third hole which faces the first hole and in which said DC bus bar penetrates, and a fourth hole which faces the second hole and in which said AC bus bar penetrates; wherein a second wall of said terminal box which is different from the first wall of the terminal box provides a DC power terminal portion for connecting with a DC side cable which connects to the DC power source, and an AC power output portion for connecting with a motor side cable which connects to the motor; wherein said terminal box provides a partition which separates a space in the terminal box; wherein said third hole and said DC power terminal portion are formed at a side wall of said terminal box which forms a first space separated by said partition; and wherein said fourth hole and said AC power output portion are formed at a side wall of said terminal box which forms a second space separated by said partition.
