Title:
SEMICONDUCTOR MODULE PARALLEL CIRCUIT AND SEMICONDUCTOR MODULE CONNECTION BOARD
Document Type and Number:
WIPO Patent Application WO/2020/202272
Kind Code:
A1
Abstract:
This semiconductor module parallel circuit (1) is provided with a plurality of power semiconductor modules (10) and a multi-layer board (100) for connecting the plurality of power semiconductor modules (10). The power semiconductor modules (10) each have: a power semiconductor switching element; a first signal terminal connected to the gate potential of the power semiconductor switching element; and a second signal terminal connected to the source potential of the power semiconductor switching element. The multi-layer board (100) has: an external connection terminal; a first signal terminal connection pattern for connecting the first signal terminal of each of the power semiconductor modules (10); and a second signal terminal connection pattern for connecting the second signal terminal of each of the power semiconductor modules (10). The inductances of the gate wiring of the plurality of power semiconductor modules (10) from the external connection terminal to the first signal terminal connection pattern and from the second signal terminal connection pattern to the external connection terminal are equal to each other.
