Power Inverter

A power inverter that fixes a connector, in which a DC-side connector and an AC-side connector are mechanically combined, to a casing, the power inverter comprising:

• a power semiconductor module that converts a DC current into an AC current;
• a DC terminal that delivers the DC current to the power semiconductor module;
• an AC terminal that delivers the AC current to an electrical motor;
• and
• the casing that houses the power semiconductor module, wherein
• the DC terminal and the AC terminal are arranged on one side face of the casing,
• the one side face of the casing forms a rectangular shape that is configured by a side formed in a widthwise direction and a side formed in a longitudinal direction,
• the DC terminal is configured by a positive-side DC terminal and a negative-side DC terminal,
• the AC terminal is configured by a U-phase side terminal, a V-phase side terminal, and a W-phase side terminal,
• the positive-side DC terminal and the negative-side DC terminal are arranged to be aligned along one side, which is formed in the widthwise direction, of the one side face of the casing, and
• the U-phase side terminal, the V-phase side terminal, and the W-phase side terminal are arranged to be aligned along one side, which is formed in the longitudinal direction, of the one side face of the casing.
