WIPO Patent Application WO/2018/229929
Kind Code:
A1
Abstract:
Provided is a power conversion device reduced in size. The power conversion device is provided with a case (30), a power module (4), a smoothing capacitor (5), and a high-voltage connection portion (8). The power module (4) is housed in the case (30). The smoothing capacitor (5) is fixed to the case (30) with a capacitor fixing bolt (54) and suppresses voltage variation. The high-voltage connection portion (8) electrically connects the power module (4) and the smoothing capacitor (5) to each other. When a position where the smoothing capacitor (5) is fixed to the case (30) with the capacitor fixing bolt (54) is defined as a capacitor fixing point (9C), the capacitor fixing point (9C) is disposed at a position avoiding a corner (5a) of the smoothing capacitor (5). The power module (4) and the smoothing capacitor (5) are approached to each other in the high-voltage connection portion (8).
