Title:
電力用半導体モジュール及び電力変換装置
Document Type and Number:
Japanese Patent JP5893126
Kind Code:
B2
Abstract:
A power semiconductor module capable of reducing variation of inductance between upper/lower arms and reducing variation of current caused by the variation of inductance. The power semiconductor module includes circuit blocks (upper/lower arms) each of which is configured by connecting self-arc-extinguishing type semiconductor elements in series; a positive electrode terminal, a negative electrode terminal, and an AC terminal that are connected to each of the circuit blocks; and wiring patterns that connect the self-arc-extinguishing type semiconductor elements of the circuit blocks to the positive electrode terminal, the negative electrode terminal, and the AC terminal, wherein the circuit block is plural in number; the positive electrode terminal, the negative electrode terminal, and the AC terminal are each disposed to be plural in number corresponding to the circuit blocks; and the positive electrode terminals and the negative electrode terminals are closely disposed.
