Abstract
An electric power converter includes a semiconductor module, a capacitor, and a DC bus bar that electrically connects them. The capacitor has a capacitor element and a capacitor terminal connected to the capacitor element. The capacitor terminals and the DC bus bar are connected to each other at least at two connecting portions. The DC bus bar has a bus bar main body portion that is connected to the semiconductor module. The two connecting portions are connected by at least a portion of the bus bar main body portion. The capacitor terminal has a terminal main body portion that is connected to the capacitor element. The two connecting portions are connected by at least a portion of the terminal main body portion.
