power supply module

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.

Now if you go to search for vehicle voltage booster/buck Marine boost voltage power supply module, you will find that the price difference is very big. The cheap ones are more than ten yuan, and the more expensive ones are more than 1,000 yuan. Why is the price difference between the cheap and the expensive so big? What are the main differences?

There is a big difference in price between cheap and expensive. In fact, this is mainly because it is used in different occasions. Thousands of dollars are generally used in   vehicle voltage booster/buck Marine boost voltage power supply module systems. This kind of power module has high requirements on performance, parameters, life and other aspects, and the price will be more expensive, and this kind of power module is a high-frequency voltage switching Marine boost voltage power supply with multiple independent outputs, which is very important to the production process, etc. The requirements in all aspects are also relatively high, so this will be more expensive.
