Electromagnetic interference is the most common problem in electronic circuit design. Designers are always looking for ways to completely eliminate or reduce electromagnetic interference, or EMI. But to completely eliminate EMI interference, the first thing you need is to understand what EMI is and what its propagation process is. This article will give a general introduction to the EMI propagation process.
EMI is a general term for electromagnetic interference, but in fact, electromagnetic interference is divided into two types, one is to transmit interference, and the other is radiation interference. Conducted interference is mainly caused by interference signals generated by electronic devices transmitted through wires or common power lines, causing interference with each other. Further subdivision, conducted interference is divided into common mode interference and differential mode interference.
EMI propagation process
The propagation process of EMI mainly passes through three parts, the interference source, the interference path, and the receiver. The source of interference can be understood as the interference that the device discovers and the path of infection. For the power supply, it is generally only possible to start from two aspects, either to reduce the interference source or to cut off the interference path.
To quickly understand the propagation of EMI, I want to analyze the higher harmonics of these different waveforms in Figure 2. As shown in Figure 2, I first perform FFT on several different waveforms to see how the higher harmonics are distributed. . The image can be clearly understood through the image.
This paper introduces the process of EMI electromagnetic interference propagation in the way of graphic and textual. It can be seen that the process of electromagnetic interference propagation is not simple, but it is not complicated and difficult to understand. Only after fully understanding the principle of EMI can EMI be effectively evaded and suppressed. I hope everyone can have a better understanding of EMI after reading this article.
PCD Inserts
PCD Inserts
OPT Cutting Tools Co., Ltd specialize in offering a comprehensive gamut of PCD diamond inserts, Some of our major product include PCD milling inserts and PCD turning inserts. Then, how to identify the different of them?
Turning is machining that is generally conducted on a lathe. To make it easier to comprehend turning, imagine the machining of a car shaft for example. The workpiece is held by both ends and rotated. Then a tool on a tool post or, if manual, held by hand is moved into the workpiece to carry out the machining.
Milling is opposite to that of turning.(major product: pcd inserts PCD cutting inserts PCD Milling Inserts PCD Grooving Inserts) When milling the workpiece is stationary and the tool is rotated. As the tool rotates one or more of the cutting edges engages with the workpiece and removes material. Therefore due to the action of the cutting edges coming into and out of contact with the workpiece the machining is interrupted machining. As the cutting edges engage and disengage with the workpiece the cutting edges are subjected to severe thermal shock. This is due to the rapid temperatures increase due to friction during the cut and rapid cooling as this cutting edge disengages from the workpiece. Therefore, to enable and achieve highefficiency machining, cutting tool manufacturers strive to improve and develop tool materials and cutting edge geometries. For milling, it is important to select a tool grade material that can withstand severe working conditions and a cutting edge geometry that can maximize the performance of the cutter.
Generally, PCD inserts are identified by different geometry by using letters of the alphabet. A wide range of geometries are listed as standard, Here we present some of PCD diamond inserts which widely used.
