Abstract: A current transformer (10) includes a magnetic core, a first primary-side winding, a second primary-side winding, and a first secondary-side winding. The magnetic core includes a first magnetic core structure, a second magnetic core structure, and a third magnetic core structure. The first magnetic core structure is connected to the second magnetic core structure to constitute a first closed magnetic circuit, the first magnetic core structure is connected to the third magnetic core structure to constitute a second closed magnetic circuit, and the first magnetic core structure is a magnetic core structure common to the first closed magnetic circuit and the second closed magnetic circuit.
