Abstract

The invention discloses a voltage transformation device, which comprises a circuit board, a voltage transformation module, and first to fourth wires. The transforming module includes a first transforming unit, arranged on the circuit board, having a plurality of first pins and a plurality of second pins; and a second transforming unit, arranged on the circuit board and connected with the first transforming unit Adjacent, there are a plurality of third stitches and a plurality of fourth stitches. The first wire is used to electrically connect the first pin; the second wire is used to electrically connect the second pin; the third wire is used to electrically connect the third pin; and the fourth wire is used to electrically connect the first pin. Four pins. The first pin and the third pin are located on a first side of the transformer module, the second pin and the fourth pin are located on a second side of the transformer module opposite to the first side, and the first pin and the third pin are in phase adjacent.

Description

technical field [0001] The present invention relates to a transformer, in particular to a transformer with freely determined center tap. Background technique [0002] Since the middle tap line of a conventional transformer is fixed, the primary terminal and the secondary terminal are also fixed. When multiple transformers are placed side by side on the circuit board, two adjacent transformers are usually adjacent to different sides (for example, the primary side of the first transformer is adjacent to the secondary side of the second transformer), in order to avoid A high-voltage discharge path is generated between the primary side and the secondary side of the transformer, which usually increases the distance between the transformers. However, increasing the separation distance between different transformers also means that more printed circuit board (PCB) space is required, which requires more board cost, so a method that can save transformer layout area is needed. Cont...
