Disclosed is a core for a current transformer, which forms an upper core in a round shape, and is disposed at a position lower than the center of a power line having both ends of the upper core received, thereby minimizing the stress of a magnetic path, and increases the permeability, thereby enhancing the magnetic induction efficiency. The disclosed core for the current transformer includes an upper core curved in a semi-circular shape to have a receiving groove formed therein, and having both ends extended downwards to be disposed to be spaced apart from each other and a lower core disposed on the lower portion of the upper core, and having both ends extended upwards to be disposed to face both ends of the upper core.

Core for current transformer

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.

Current transformer module and power supply device including the same

Disclosed is an LED lamp using a switching circuit, configured to prevent occurrence of electric shock caused by a contact of a conductive metal or the human body by arranging the switching circuit between a first rectifier circuit and an LED circuit. The disclosed LED lamp using a switching circuit connects the switching circuit to at least one line among a plurality of lines connecting a rectifier circuit and an LED circuit, wherein the switching circuit may comprise: a switching element comprising at least one from among an SCR, a TRIAC, a TR, and an FET; and a driving element comprising at least one from among a capacitor, a TVS, a ZENER, a SIDAC, a resistance, and an inductor.
