What are the basic components of industrial switching equipment power supply? Only by understanding the development trend of switching power supply for industrial control equipment, talents have a clear understanding of the market demand, can they make accurate judgments about the company to serve our customers. Ability to do what customers want and do what customers want. Let's take a closer look at the basic components of an industrial switching equipment power supply, which is divided into four parts:
Main circuit: The main circuit from the AC grid input to the DC output. It mainly includes input filter, rectifier filter, inverter, output rectifier filter.
(1) Input filter: Its function is to filter the clutter existing in the grid and prevent the clutter generated by the machine from reacting to the public grid.
(2) Rectification and filtering: The AC power of the grid is directly rectified into a smooth DC power for the purpose of level change.
(3) Inverter: converts the rectified direct current into high frequency alternating current, which is the middle part of the high frequency switching power supply. The higher the frequency, the smaller the ratio of volume, weight and output power.
(4) Output rectification and filtering: according to the load demand, provide a stable and stable DC power supply.
