Abstract: A method for manufacturing a two-step core current transformer is provided to increase the size of a magnetic field induced to the core without the change of the dimension of the core by making the two-step core. A current transformer includes a two-step core and a secondary coil. The secondary coil is wound around the two-step core to form a magnetic field to the same direction. The two-step core has an annular solenoid shape. The current transformer increases the size of the magnetic field induced to the core without the resonant frequency, the change of the number of turns of the secondary coil, and the dimension of the core using the two-step cores. The output of the current transformer is increased using the two-step core.
