Abstract
A power supply device includes a current transformer module capable of adjusting a power induction ratio in order to induce a certain power even when the current of a power line is changed and the current transformer module capable of minimizing the loss in power conversion while providing a certain power even when the current of the power line is changed. The disclosed current transformer module includes a magnetic core constituting a closed loop, a plurality of unit coils wound around the magnetic core, and a switch unit connected to the plurality of unit coils, and the plurality of unit coils include a plurality of unit coils for power-generation.
