Abstract
The invention is applied to the technical field of transformers, and provides a power transformer for a computer. The power transformer for the computer comprises a plurality of magnetic circuits formed by a plurality of magnetic cores and a combined winding surrounding the magnetic circuits. The combined winding comprises a planar conductor winding and a printed circuit board winding. The magnetic cores are continuously and sequentially inserted into and surrounded by the combined winding in a direction perpendicular to the magnetic circuits, so that the magnetic circuits are surrounded by the combined winding respectively. The planar conductor winding is used as a power input end, a 12V output end and a 5V output end. The printed circuit board winding is used for -5V power output, -12V power output and standard standby power output respectively. An equivalent winding formed by combining the planar conductor winding and the printed circuit board winding is utilized, so that the input and output requirements of different currents and different voltages are met; and heating points of the transformer are scattered through the magnetic circuits, so that the radiation environment of the transformer is improved, and the output power of the transformer is improved.
