Abstract
A gate drive circuit includes one output element, a constant current drive circuit, and a constant voltage drive circuit. The output element outputs a gate drive signal to a gate of a gate driven switching element. The constant current drive circuit causes the output element to output the gate drive signal with a constant current. The constant voltage drive circuit causes the output element to output the gate drive signal with a constant voltage.
