POWER SEMICONDUCTOR DEVICE

Title:

POWER SEMICONDUCTOR DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/179547

Kind Code:

A1

Abstract:

The present invention relates to a power semiconductor device, which performs power conversion by driving in parallel three or more power semiconductor elements, and the purpose of the present invention is to reduce variance of a voltage to be applied to between the terminals of each of the power semiconductor elements, and to improve service-life of the power semiconductor elements and reliability of the power semiconductor device. In order to achieve the purpose, in this power semiconductor device, which is provided with three or more power semiconductor elements (701-704) that are aligned and mounted on metal wiring (4), and metal wiring (5) different from the metal wiring (4), and which has one terminal of each of the power semiconductor elements connected to the wiring (4), and another one terminal thereof connected to the wiring (5), the resistance value of the metal wiring (4) in a region where the power semiconductor elements (701-704) are mounted is higher in the downstream than that in the upper stream in the current flowing direction.
