We all know that the switching power supply in the main heat components for semiconductor switching tubes, power diodes, high-frequency transformers (switching power supply transformer), filtering inductors and so on. Different devices have different methods of controlling heat generation. Generally speaking, the switching power supply transformer will appear the phenomenon of heat generation after a long time of use. Today Eahunt power adapter manufacturer to explain to you, what causes the switching power transformer heat and what are the methods to reduce the switching power transformer heat?

In fact, the reason is very simple, because the switching power supply transformer is added to the switching tube power transformer, in the circuit in addition to the ordinary transformer voltage conversion function, but also both insulation isolation and power transfer function is generally used in the switching power supply and other high-frequency circuits involved in the occasion. From this point of view, the switching power supply transformer heat because of the switching tube heat, and the switching tube heat is caused by the loss, the switching tube loss by the switching process loss and pass-state loss of two parts, therefore, to reduce the heat can be the following methods.

Method I. It is more important to reduce the loss by designing better control mode and buffer technology, such as using soft switching technology, which can greatly reduce this loss.

Method two, for high-frequency magnetic materials caused by the loss, try to avoid the skin effect, for the effect caused by the skin effect, can be used to solve the multi-stranded fine enameled wire and winding method.

Method three, to reduce the pass-state loss can be reduced by selecting a low pass-state resistance of the switching tube to reduce the pass-state loss.

Method 4, for the rectification of the secondary side of the transformer can choose a more efficient synchronous rectification technology to reduce the loss.

Method 5, the switching process loss is due to the size of the gate charge and switching time caused by reducing the switching process loss can choose to switch faster, shorter recovery time to reduce the device.

Method six, reduce the power diode heat, AC rectifier and buffer diodes, in general, there will not be a better control technology to reduce losses, you can choose high-quality diodes to reduce losses.
