    摘要: A power conversion device for a vehicle includes: a power module that includes a switching device and, upon operation of the switching device, converts DC power into AC power to be supplied to an electric machine for driving a vehicle; a capacitor module that includes a smoothing capacitor element, an input-side power source terminal for receiving DC power, and an output-side power source terminal for supplying DC power to the power module; and a noise removal capacitor for removing noise, wherein: the noise removal capacitor is built in the capacitor module, and the noise removal capacitor is electrically connected to the input-side power source terminal in a position where a distance between a connection position of the noise removal capacitor and the input-side power source terminal is less than a distance between a connection position of the noise removal capacitor and the output-side power source terminal of the capacitor module.
