Mongolia the switching frequency of the AC-DC switching power supply module?(1)
What is the operating frequency of Mongolia 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.
The synchronous rectification technology uses field effect transistors (MOSFETs) with small on-resistance and low withstand voltage to replace ordinary rectifier diodes. Since the synchronous rectifier MOSFET has the characteristics of low on-resistance (generally only a few mΩ), small leakage current when blocking, and high switching operating frequency, it can greatly reduce the power consumption of the power rectifier part and make the working efficiency of the power system obvious. It is improved, but the realization of synchronous rectification is more complicated than diode rectification in specific applications. In the application of low voltage and high current output of switching power supply, synchronous rectification technology has a good application prospect.
Mongolia 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:
