Design of Switch Transformer about the Push-Pull Switch Power Supply

Abstract:

the push-pull switch power is a kind of form in the family. It has the characteristics of good voltage output, high efficiency, the simple circuit and so on. On the design of the push-pull switch power supply, the key and difficult point is the design of switch transformer. Taking the switch transformer of a push-pull switching power supply as the research object and based on the design requirements, this paper aims to realize the calculation of the coil turns in switching transformer. Meanwhile, under the consideration of the skin effect and the proximity effect and the choices of switch transformers wires and the methods of wires winding, the design of switch transformer of the push-pull switch power supply has been completed by circuit simulation and implementation.
