In the switching power supply for the development of new products, grounding settings as one of its important research and development links, is the power supply engineers must be cautious, and therefore is also considered an important step in the process of switching power supply technology progress. So why do switching power supplies need to be grounded? What are the common ways of grounding settings? Today, Eahunt briefly introduces this indispensable link in the application of power supply technology.
Usually, in the current switching power supply product design process, whether it is a domestic product or a foreign product, the grounding method has a variety of ways, such as single-point grounding, multi-point grounding and mixed grounding methods are often used. In general, the single-point grounding technology in switching power supply technology is usually applied to simple circuits, the grounding area between different functional modules, and low-frequency (f10MHz) circuits should be used when the multi-point grounding or multi-layer board.
Why do switching power supplies need to be grounded? During the initial development of power supply technology, in order to prevent electrical and electronic equipment from being harmed by lightning strikes, engineers chose to use grounding to divert the strong currents that are generated instantaneously, thus protecting the electrical or electronic equipment. This can be effective lightning generated by the lightning current through the lightning rod into the earth, and to protect equipment and buildings. This simple grounding setup has since evolved into a grounding setup that is capable of handling instantaneous voltages or excessive currents. In addition to the protection of electronic equipment, grounding is also an effective means of protecting personal safety, when some reason caused by the phase line and the equipment casing touch, the equipment casing will have a dangerous voltage, the resulting fault current will flow through the PE wire to the earth, thus playing a protective role.
The above is Eahunt for the switching power supply grounding set up a brief share, I hope to be able to help people who just want to understand the power supply products, to play some answers and help.
