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

Due to the wide variety of integrated circuits used in communication equipment, their power supply voltages are also different. In the communication power supply system, a high-frequency DC-DC isolation module power supply with high power density is used, which is converted from the intermediate bus voltage (usually 48V DC) to Various DC voltages are required, which can greatly reduce losses, facilitate maintenance, and are very convenient to install and increase. Generally, it can be directly installed on the standard control board, and the requirement for the secondary power supply is high power density. Due to the continuous increase of communication capacity, the capacity of communication power supply will also continue to increase.

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

Oman Choosing the switching frequency of the Marine boost power supply does not mean choosing the switching frequency of the Marine boost 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 Marine boost 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:
