Knowledge of power supply modules

1. What is the basic working principle of the power supply? By running the high frequency switching technology, the higher AC voltage will be input (AC) Convert to the lower DC voltage required for PC computer operation (DC). 2. What is the workflow of the power module? When the commercial power enters the module power supply, the high-frequency clutter and interference signals are first removed through choke coil and capacitor filtering, and then high-voltage direct current is obtained through rectification and filtering. Then the direct current is converted into high-frequency pulsating direct current through the switching circuit, and then the high-frequency switching transformer is sent to step-down. Then filter out the high-frequency AC part, so that the output is relatively pure low-voltage direct current for the computer. 3. How to define the isolation of power supply module? The isolation of power supply modules is generally divided into two types: one is. Isolation between input and output; That is, the input and output are not common ground; The other is the isolation between output and output; Multiple sets of outputs are isolated from each other and do not interfere with each other. The power module may be very strange to us, because we seldom use or see this kind of electrical component in our daily life, but if we observe it carefully, there is such an electrical component in the chassis of our desktop computer. That is, what we usually call the power supply. The power supply module is a power supply that can be directly mounted on the printed circuit board. It has strong professionalism and a relatively high-tech range of use, it is used in some places with high requirements, especially for voltage. For example, it supplies power to loads such as application specific integrated circuits, digital signal processors, microprocessors, memories, field programmable machines, etc. Dear Customer: Hello, our company is a high-quality development group with strong technical force, providing high-quality products, complete solutions and superior technical service companies for the majority of users.
