| Abstract: | The working principle of a kind of atmospheric pressure low temperature plasma power supply used for the surface processing of fabric and it＇ s control circuit are introduced in this paper. A kind of stable, uniform, soft and low temperature plasma is produced according to the fabric surface treatment process. High voltage power supply adopts IGBT as switching element for DC chopping and full bridge inverting, to realize the efficiency and minimization of the high frequency high voltage power supply. A peripheral circuit comprised of computer control unit is adopted by control system to realize automatic adjustment, power failure protection and soft start function of power supply. The practical application of the plasma high frequency voltage power supply in the textile material, the results show that application of the technology can improve the efficiency of power supply, at the same time, can also suppress the surge voltage and peak current quickly and efficiently. The performance of the textile material surface treatment is improved. |
