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

Drive module power supply
The frequency converter power supply is mainly used for the frequency conversion and speed regulation of the AC motor. The main circuit of the inverter power supply adopts the AC-DC-AC scheme. The power frequency power supply becomes a fixed DC voltage through a rectifier, and then a PWM high-frequency converter composed of high-power transistors or IGBTs inverts the DC voltage into an AC output with variable voltage and frequency. The output waveform of the power supply is similar to a sine wave. It is used to drive the AC asynchronous motor to realize stepless speed regulation.

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

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