Title:
GATE DRIVE CIRCUIT AND SWITCHING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/137826
Kind Code:
A1
Abstract:
An insulated gate drive circuit (1) which drives a semiconductor switching element comprises: a transmission unit (10) which generates a power signal that acts as the basis for gate driving of a semiconductor switching element; a first insulated element (3) which transmits a power signal in an electrically insulated state; a receiving unit (12) which performs gate driving of a semiconductor switching element by means of a power signal output from the first insulated element (3); and a transmission circuit for transmitting the state detected by the receiving unit side to the transmission unit side. The transmission circuit transmits the abovementioned state by branching part of the power signal using an insulated path (3c) distinct from the path which transmits the power signal on the first insulated element (3).
