<p>A current transformer, a current detection circuit, and a current detection method are provided. The occupation space of a lay-out board in a print circuit board can be reduced, and the distributed inductance can be decreased at the same time. The current transformer comprises a hollow magnetic core(1).The hollow magnetic core(1) is used for arranging a current carrying conductor(5) to be detected in a loop to be detected(41).A coil(2) is wound on a sidewall of the hollow magnetic core(1) along the direction in parallel with the center axis of the hollow magnetic core(1).The coil(2) have two input terminals(3,4).The two input terminals(3,4) are used for electrically connecting with a detection signal output circuit(43).</p> |
