Abstract (en)

Disclosed are a current transformer for power supply, and a method for manufacturing the same. The current transformer for power supply comprises: a first core formed of a magnetic substance, and having a loop shape with a gap at one side thereof; and a supporting core formed of a magnetic substance, and disposed at one or more sides of the first core so as to block the gap. Accordingly, power supply can be smoothly performed at a small current region, and a power supply subject is prevented from being damaged at a large current region. Furthermore, the number of turns of a coil can be reduced, and an entire size of the current transformer for power supply can be made to be small.
