technical field [0001] The invention relates to a high-voltage generating circuit and a static elimination system using the circuit, in particular to an interlocking high-voltage generating circuit capable of realizing symmetrical discharge and a static eliminating system using the interlocking high-voltage generating circuit. Background technique [0002] At present, whether it is the electronics industry, the liquid crystal industry or the precision manufacturing industry, higher and higher requirements are put forward for electrostatic protection, which means that anti-static equipment, such as various static eliminators, must continue to improve their performance and have Wider control range, lower participation voltage and faster static elimination time. [0003] The step-up circuit used in the DC static eliminator in the prior art often alternately transforms positive and negative voltages, so that the discharge electrodes generate positively charged ions or negatively...

AI Technical Summary

Problems solved by technology

[0003] The step-up circuit used in the DC static eliminator in the prior art often alternately transforms positive and negative voltages, so that the discharge electrodes generate positively charged ions or negatively charged ions, but cannot achieve symmetrical discharge, and generate positive and negative charges at the same time ions, so the efficiency of static elimination is relatively low, and it is prone to balance voltage fluctuations

[0004] At the same time, the static eliminators disclosed in the utility model patent with the application number 201220321850.8 and the invention patent with the application number 201110453355.2 are various static eliminators such as the existing single-point fan, wind bar and wind snake. The static electricity control in the local area around the workshop or the installation point can meet the standard, but because of its single-point installation, it can only cover local characteristics, and there will always be static protection dead spots in the anti-static protection area, which will cause some electrostatic damage problems. There are hidden dangers

[0005] On the other hand, currently used fans and air rods have strong wind blowing out, such as the AC ion fan described in the patent No. CN201220501244, when applied in a clean room environment, it may cause the air flow in the clean room to be disturbed. Affect the cleanliness of the clean room; and the static eliminator without wind blowing, its ion flying distance is shorter than the static eliminator with fan, and it is more difficult to cover the entire room, so whether it is static eliminator with fan or without Fan static eliminators, they all have certain defects
