Abstract
A current detection circuit configured to detect a resonant current of a power supply circuit. The power supply circuit includes a resonant circuit that has an inductor and a first capacitor having a first end and a second end. The current detection circuit includes a second capacitor having a first end and a second end, and a non-linear circuit provided between the second end of the second capacitor and the second end of the first capacitor. The first end of the second capacitor is coupled to the first end of the first capacitor.
