Document Type and Number:
WIPO Patent Application WO/2022/065150
Kind Code:
A1
Abstract:
A signal transmitting device, according to the present invention, for example, transmits a drive signal of a gate drive transistor between a primary circuit system and a secondary circuit system while insulating between the primary circuit system and the secondary circuit system, and comprises: a first external terminal configured to connect a grounding end of the secondary circuit system; a second external terminal configured so that the terminal voltage changes depending on whether the first external terminal is in an open state; and an open detection circuit that monitors the terminal voltage of the second external terminal and detects whether the first external terminal is open.
