What is the role of switching power transformer
Release time:

The switching power supply transformer and the switching tube together form a self-excited (or he excited) type of intermittent oscillator, which modulates the input DC voltage into a high-frequency pulse voltage.
Play the role of energy transfer and conversion. In the flyback circuit, when the switch tube is turned on, the transformer converts electrical energy into magnetic field energy for storage, and releases it when the switch tube is turned off. In the forward circuit, when the switch tube is turned on, the input voltage is directly supplied to the load and the energy is stored in the energy storage inductor. When the switch is cut off, the energy storage inductor is then freewheeling to the load.
Convert the input DC voltage into the required low voltage.

What is the main role of the filter in the power line
As the name suggests, it is a device for filtering waves. "Wave" is a very broad physical concept. In the field of electronic technology, "wave" is narrowly limited to the process of describing the fluctuation of various physical quantities over time. This process is converted into a time function of voltage or current through the action of various sensors, which is called a time waveform of various physical quantities, or a signal.

Transformer short circuit fault reason
There are many reasons for transformer internal faults and events caused by short circuit at transformer outlet, which are related to structural planning, quality of raw materials, technological level, operating conditions and other factors, but the selection of electromagnetic wire is the key. From the analysis of the transformer in recent years, it can be seen that there are roughly the following reasons for the electromagnetic wire.

Coil inductance value considerations
The inductance value in the total loop with different connection modes is different. When the four coils are connected in parallel, the inductance value is the smallest and the current in the loop is the largest; when the four coils are in reverse series, the inductance of the loop is the largest and the current of the loop is the smallest. No matter from the analysis of the current flowing through each coil or the energy distributed from the coil, the connection mode of four coils is the most appropriate.
