Title:
SEMICONDUCTOR DRIVING DEVICE AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/193834
Kind Code:
A1
Abstract:
According to the present invention, on/off determination units 23H, 23L output on/off determination signals SonH, SonL which indicate on/off states of switching elements M1, M2. Abnormality detection units 24H, 24L output abnormality detection signals SfaH, SfaL which indicate the presence or absence of abnormality of the switching elements M1, M2. State signal generation units 21H, 21L output state signals SstH, SstL on the basis of the on/off determination signals SonH, SonL and the abnormality detection signals SfaH, SfaL. Insulating communication units 20H, 20L transmit state signals output from the state signal generation units 21H, 21L while securing insulation between the state signal generation units 21H, 21L and a control unit 10. The control unit 10 generates on/off command signals SctlH, SctlL for driving the switching elements M1, M2, respectively.
