Title:
POWER CONVERSION DEVICE AND BI-DIRECTIONAL SWITCH
Document Type and Number:
WIPO Patent Application WO/2023/062943
Kind Code:
A1
Abstract:
Provided is a bi-directional switch having: a first silicon carbide transistor; a first diode provided in series with the first silicon carbide transistor, the first diode having a lower on voltage at the rated current of the bi-directional switch than a built-in diode in the first silicon carbide transistor; a second silicon carbide transistor provided in parallel with the first diode; a second diode provided in series with the second silicon carbide transistor and provided in parallel with the first silicon carbide transistor, the second diode having a lower on voltage at the rated current of the bi-directional switch than a built-in diode in the second silicon carbide transistor; and a connection line for connecting a first contact point between the first silicon carbide transistor and the first diode and a second contact point between the second silicon carbide transistor and the second diode.
