Summary: | A gate drive circuit includes a resistor, a current detector that detects a current flowing through the resistor, and a gate driver. The gate driver applies an electric signal between a gate terminal and a source terminal of a module to drive a switching semiconductor element. One end of the resistor is connected to a drain terminal, the opposite end of the resistor is connected to one end of the current detector, and the opposite end of the current detector is connected to the gate driver. The current detector outputs a detection value of the current to the gate driver, and the gate driver changes a gate drive speed of the switching semiconductor element according to the detection value. |
