Abstract

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 (151) formed of a magnetic substance, and having a loop shape with a gap (G) at one side thereof; and a supporting core (161) formed of a magnetic substance, and disposed at one or more sides of the first core (151) so as to block the gap (G). 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. (Figure 7)
