(Summary description)What is the impedance matching principle of the online plasma cleaning machine, and what are the knowledge points: The impedance adapter seems to be a bridge connecting the reaction chamber, electrode and plasma generator of the online plasma cleaner. Therefore, how does the impedance matching of the online plasma cleaner work? How does it work? Impedance matching is usually used in vacuum online plasma cleaning equipment. The reaction chamber, electrode, plasma generator, etc. are called loads. In a DC circuit with a load, the load resistance is equal to the internal resistance of the power supply as a necessary condition for load matching. This Z high-power DC loop theorem also exists in the corresponding AC loop. Let me explain to you what the next high-frequency circuit with load impedance z looks like. Set the internal impedance of the power supply, that is, the output impedance to (a+jb)Ω. In order to meet the output requirements of the Z high-power load, the load impedance needs to be "matched" with the output impedance of the high-frequency generator. Conjugate matching can make the total impedance become a pure resistance, that is, the load impedance Z must be (a-jb)Ω at this time. In the design of the online plasma cleaner, in order to control the high-frequency current in the loop within a reasonable value range, the output impedance of the high-frequency generator is usually designed as a pure resistance, generally 50Ω. In general, the high-frequency discharge impedance is the capacitive impedance. Due to the changes in the discharge conditions of the reaction chamber in the online plasma cleaner, the high-frequency discharge impedance will change in value. Therefore, it is necessary to adjust the impedance of the matching network and the discharge impedance to achieve Simulate the addition of load impedance to make it consistent with the output impedance of the high-frequency generator to achieve matching. In other words, the matching network must be adjusted through various discharge conditions so that the analog load is also equal to 50Ω. In addition, in order to avoid unnecessary power loss in the matching network due to heat, the location of the matching network is also carefully set. This is one of the factors that affect the matching effect of the online plasma cleaning machine. In future articles, Chengfeng Zhizao will again Talk to everyone.
