Abstract
An inverter device includes an inverter outer peripheral wall, a high voltage board, a control board, and an arm switch unit. The inverter outer peripheral wall has an inner peripheral surface. The high voltage board and the control board extend in a direction orthogonal to an axial direction. In the high voltage board and the control board, an outer peripheral end extends in a ring shape in a circumferential direction along the inner peripheral surface. In the arm switch unit, a drain terminal and a source terminal are connected to the high voltage board, and a gate terminal and a driver source terminal are connected to the control board. Multiple arm switch units are arranged in the circumferential direction along the outer peripheral end.
