Abstract
A driver circuit 101 is connected to a control terminal of a semiconductor switching element 1. The driver circuit 101 includes 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 output from the output control circuit 4 is input to a dead time adjustment circuit 13. The dead time adjustment circuit 13 includes a delay circuit which can delay the rising edge and the falling edge of the pulse signal output from the output control circuit 4 on the basis of signals from temperature analog output circuits 11 and 12. An output from the dead time adjustment circuit 13 is input to the drive circuit 5. The drive circuit 5 outputs a drive signal to an output terminal 51 of the driver circuit 101.
