Abstract
A semiconductor device includes a main insulated gate type switching element having a gate electrode and controllable by a gate voltage applied to the gate electrode, a current detecting insulated gate type switching element connected in parallel to the main insulated gate type switching element, a detecting resistor for detecting a current flowing in the current detecting insulated gate type switching element, a gate controlling element capable of controlling the gate voltage by a drop voltage in the detecting resistor, and a gate control relieving element for relieving a varying speed of the gate voltage varied based on an operation of the gate controlling element.
