North Korea the switching frequency of the AC-DC switching power supply module?(1)

The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.

What is the operating frequency of North Korea 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.

North Korea 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:
