PROBLEM TO BE SOLVED: To provide an inverter unit capable of accommodating an inverter and a member related to the inverter in a compact manner.SOLUTION: An inverter unit 100 comprises: an inverter 44 that includes three respective phase terminals 44u, 44v, 44w and performs conversion between DC power and three-phase AC power; a bus bar 110 including a three- terminal fastening part 110a connected to the three respective phase terminals 44u, 44v, 44w and a three-phase wiring fastening part 110e connected to three-phase wiring 73; a current sensor 120 for detecting each phase current value of three-phase current; and an inverter case 47 for accommodating the inverter 44, bus bar 110, and current sensor 120. The inverter 44 has a box shape; the bus bar 110 is formed in an approximate U-shape while containing a board 122 of the current sensor 120 and faces a face including the shortest side 44x of three sides of the inverter 44. The bus bar 110's width L2 along the shortest side 44x is formed to be thinner than a length L3 of the shortest side 44x of the inverter 44.SELECTED DRAWING: Figure 7 |
