Title:
SEMICONDUCTOR SWITCHING ELEMENT DRIVER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2015/071994
Kind Code:
A1
Abstract:
A driver circuit (101) is connected to the control terminal of a semiconductor switching element (1). The driver circuit (101) comprises: an input circuit (3) connected to an input terminal (50); and an output control circuit (4) connected to the input circuit (3). A pulse signal outputted by the output control circuit (4) is inputted to a dead time adjustment circuit (13). The dead time adjustment circuit (13) includes a delay circuit. This delay circuit can delay, on the basis of signals from temperature analog output circuits (11, 12), the leading and trailing edges of the pulse signal outputted by the output control circuit (4). An output from the dead time adjustment circuit (13) is inputted to a drive circuit (5). The drive circuit (5) outputs a driver signal to an output terminal (51) of the driver circuit (101).
