SWITCHING ELEMENT DRIVING CIRCUIT

摘要

A switching element driving circuit of the present invention is provided with: a drive voltage generation circuit 18 for generating a drive voltage for driving a switching element 16; and a filter circuit 20 for filtering the drive voltage. The filter circuit 20 constitutes, together with an internal gate resistor 10 of the switching element 16 and an input capacitor 13 between a gate terminal 11 and an emitter terminal 15, a circuit having a step response represented by a second order transfer function and has circuit constants set so that the damping factor of the transfer function has a value within a certain range.
