AC-DC power module

What is the operating frequency of Haiti the AC-DC switching 24V input power supply module? What factors need to be considered when choosing an AC-DC switching 24V input power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.

The high-voltage DC power supply for electrostatic precipitator has been developed in China. The commercial power is rectified into DC, and the full-bridge zero-current switch series resonant inverter circuit is used to invert the DC voltage to a high-frequency voltage, which is then boosted by a high-frequency transformer, and finally rectified. for DC high voltage. Under the condition of resistive load, the output DC voltage reaches 55kV, the current reaches 15mA, and the operating frequency is 25.6kHz.

Haiti Choosing the switching frequency of the 24V input power supply does not mean choosing the switching frequency of the 24V 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 24V 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:
