摘要：
A short-circuit protection circuit (12) configured to protect a switching element from an overcurrent includes: a potential decreasing means for decreasing a potential of a gate terminal when a main circuit current is an overcurrent; a feedback means for performing feedback control on an amount of a decrease in the gate potential caused by the potential decreasing means according to a current amount of the main circuit current; and a phase advancing means for performing phase advance compensation in a feedback loop under the feedback control.
