Costa Rica the switching frequency of the AC-DC switching power supply module?(1)

What is the operating frequency of Costa Rica the AC-DC switching LED advertising screen power supply module? What factors need to be considered when choosing an AC-DC switching LED advertising screen power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.

In the early 1980s, the research on the distributed high frequency switching power supply system basically focused on the research of the converter parallel technology. In the mid-to-late 1980s, with the rapid development of high-frequency power conversion technology, various converter topologies appeared one after another. Combined with large-scale integrated circuit and power component technology, it became possible to integrate small and medium power devices, thereby rapidly Promote the development of distributed high-frequency switching power supply system research. Since the late 1980s, this direction has become a research hotspot in the international power electronics field.

Costa Rica Choosing the switching frequency of the LED advertising screen power supply does not mean choosing the switching frequency of the LED advertising screen power supply with a good switching frequency, but the choice is suitable for your own use. Most of the current market is like this. The frequency of the AC-DC switching LED advertising screen power supply module is between 50K and 135K, and this frequency range can meet most applications. Let's discuss it. Some of the problems that AC-DC encounters when choosing switching frequency:
