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

What is the operating frequency of Oman the AC-DC switching 48V input power supply module? What factors need to be considered when choosing an AC-DC switching 48V input power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.

module combination
(1) Parallel expansion. Connecting the output terminals of the same module in parallel can enhance the output capability, but the output voltage of the parallel modules should be adjusted to be consistent to ensure relative current sharing and avoid unnecessary oscillations. For modules with large current output, the lead resistance can also be carefully designed to achieve the effect of current sharing. The number of modules connected in parallel in this way should not exceed 2. At the same time, if one of the module outputs is faulty, the entire system will not work properly. The parallel expansion connection circuit RL is the load.

Oman Choosing the switching frequency of the 48V input power supply does not mean choosing the switching frequency of the 48V input 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 48V input 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:
