Abstract
In accordance with the present invention, a multi-output transformer includes a primary bobbin provided with one primary winding unit with one input terminal and one ground terminal; a secondary bobbin provided with n(n: positive integer) number of secondary winding units with two output terminals respectively; a primary coil wound around the one primary winding unit; secondary coils wound around each of the n secondary winding units; and a pair of cores inserted into insertion holes formed inside the primary bobbin and the secondary bobbin respectively to separate the primary bobbin and the secondary bobbin.
Claims20
A multi-output transformer comprising:
- a primary bobbin including one primary winding unit with one input terminal and one ground terminal;
- a secondary bobbin including n(n:
