Abstract
A current detection device is configured by a current path through which a first current flows, a current path through which a second current flows, a switching element that switches the current paths and allows the first current and the second current to flow alternately, a common coil section through which an induction current flows by the first current and the second current, and a turn current path that alternates a first induction current flowing through the coil section by the first current and a second induction current flowing through the coil section by the second current.
