Abstract
A signal detection circuit includes: a first capacitor having a first terminal connected with a first main terminal of a switching element; a second capacitor having a first terminal connected with a second main terminal of the switching element; and a detection circuit having a differential circuit configuration. The detection circuit receives, as input signals, a signal from a second terminal of the first capacitor and a signal from a second terminal of the second capacitor, detects detection target signals based on the input signals. The detection target signals include a signal of the first main terminal of the switching element and a signal of the second main terminal of the switching element.
