Title:
SIGNAL TRANSMISSION CIRCUIT, SWITCH DRIVING DEVICE, AND POWER MODULE
Document Type and Number:
WIPO Patent Application WO/2019/167827
Kind Code:
A1
Abstract:
A filter circuit (80), having a first rise delay circuit (82a) for delaying the rise timing of a first shifted signal by a prescribed time and outputting the result, and a first fall delay circuit (82b) for delaying the fall timing of a second shifted signal by a prescribed time and outputting the result. The first rise delay circuit (82a) is configured so that a second rise delay signal does not follow a variation towards the side in which a first voltage decreases, and follows a variation towards the side in which the first voltage increases. The first fall delay circuit (82b) is configured so that a second fall delay signal does not follow a variation towards the side in which the first voltage decreases, and follows a variation towards the side in which the first voltage increases.
