Abstract
A power conversion device includes a filter capacitor to accumulate therein DC power, and an element unit including a semiconductor element module to perform a switching operation for converting the DC power accumulated in the filter capacitor into AC power. The filter capacitor and the element unit are disposed in the same casing. A heat-resistant capacitor having a higher heat resistance than the filter capacitor is connected to the element portion by using a connection conductor, and is also connected to a busbar different from the connection conductor. An electrical connection between the filter capacitor and the element unit is established through the busbar, the connection conductor, and the heat-resistant capacitor.
