Abstract
A signal detection circuit detects, as a detection target signal, a signal of a main terminal of a switching element by comparing the detection target signal with a reference signal. The signal detection circuit includes: a signal generation unit generating the reference signal; a first capacitor having a first terminal connected with the main terminal of the switching element; a second capacitor having a first terminal connected with an output terminal of the signal generation unit; and a detection circuit receiving, as input signals, a signal output from a second terminal of the first capacitor and a signal output from a second terminal of the second capacitor, and the detection circuit detecting the detection target signal based on the input signals.
