Abstract
A driving circuit includes first and second driving units connected in parallel to each other, wherein both the first and second driving units start to supply a gate current to a gate of a switching device in a turn-on operation of the switching device, when a gate voltage of the switching device increases and has reached a threshold voltage of the switching device, the first driving unit continues to supply the gate current, and the second driving unit stops supply of the gate current before the gate voltage has reached the threshold voltage.
