Abstract
A power converter includes a switching device composed of parallel-connected semiconductor chips evenly divided into two groups. The power converter includes a positive conductor, a capacitor and an output electrode. The positive conductor includes first and second terminal portions. The output electrode includes an end portion joined to a base portion having first and second connecting portions. The output electrode is formed so as to reduce or cancel a difference existing between an inductance Lof a current path from a positive terminal of the capacitor to the first terminal portion and an inductance Lof a current path from the positive terminal to the second terminal portion, by providing a difference between an inductance Lof a current path from the first connecting portion to the end portion and an inductance Lof a current path from the second connecting portion to the end portion.
