Abstract
The present invention relates to a transformer. In the transformer, secondary winding sections are placed in both sides of a primary winding section, all terminals of the secondary winding sections are used as output terminals, and an input terminal is placed in the opposite side to the output terminals. Therefore, a return wire in the high-voltage output side does not need to be provided, and a sufficient insulation separation distance is secured in the relation with a printed circuit board, which makes it easy to implement a circuit. Further, improved efficiency is obtained over a conventional transformer, there is a significant reduction in cost, and products using the transformer can be small in size. The transformer includes a bobbin composed of one primary winding section having one input terminal and one ground terminal and 2n (n: positive number) secondary winding sections, each secondary winding section having two output terminals; a primary coil wound around the primary winding section; secondary coils wound around the 2n secondary winding sections; and a pair of cores that are respectively inserted into an insertion hole formed inside the bobbin.
