Title:
SEMICONDUCTOR DEVICE AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/008424
Kind Code:
A1
Abstract:
A semiconductor device (1) is provided with a positive electrode-side semiconductor element (7), negative electrode-side semiconductor element (8), positive electrode plate (4), negative electrode plate (5), alternating current electrode plate (6), positive electrode-side auxiliary electrode terminal (13), negative electrode-side auxiliary electrode terminal (14), positive electrode-side capacitor (11), and negative electrode-side capacitor (12). The positive electrode plate (4) is connected to a first positive electrode (71) of the positive electrode-side semiconductor element (7). The negative electrode plate (5) is connected to a second negative electrode (82) of the negative electrode-side semiconductor element (8). The alternating current electrode plate (6) is connected to a first negative electrode (72) of the positive electrode-side semiconductor element (7), and a second positive electrode (81) of the negative electrode-side semiconductor element (8). The positive electrode-side capacitor (11) is connected to the positive electrode plate (4), and also to the positive electrode-side auxiliary electrode terminal (13). The negative electrode-side capacitor (12) is connected to the negative electrode plate (5), and also to the negative electrode-side auxiliary electrode terminal (14).
