Nowadays, there are fewer and fewer low-frequency transformer manufacturers. Many people think that it is impossible for low-frequency transformers to be replaced by high-frequency transformers. First of all, the transformer is just a component in the power supply. Anyone who knows this thing knows that in the power supply, the step-down and output are realized by a circuit composed of many kinds of components.
So can switching power supply replace low frequency transformer? We can understand it from the following five aspects.
1. The general low frequency transformer will not be disturbed by the pulse of the switching power supply;
2. It has the function of isolating various power grid pulse interference;
3. The low-frequency transformer has anti-surge ability that the switching power supply cannot compete with, especially lightning;
4. The linear power supply made by the low frequency transformer has the best performance of introducing ripple;
5. Low-voltage switch chips can be used at the output end of the low-frequency transformer, which has high efficiency as well as isolation.
