Abstract

A transformer is provided. The transformer includes a robbin, a primary coil, a secondary coil, a first core and a second core. The robbin has a through hole. The primary coil and the second coil are winded around the robbin accordingly. The first core is disposed into the through hole. The second core has a first end and a second end coupled to the first core. The second core has a protrusion portion which is located between the first end and the second end. The protrusion portion is disposed between the first coil and the second coil.
