-
摘要: 研究了逆变式CO2弧焊电源中输出滤波电感的作用,从理论上分析了用电子电抗器取代传统铁磁电抗器的方式,并对减小滤波电感至最小值的约束条件进行了理论分析和实验研究.Abstract: The function of output filter in inverter CO2 gas shieldes arc welding machine is stUdied. Based on theoretical analysis, the way to relpace traditional inductor by electronic inductor is introduced. The condition that limit the minimization of the filter inductor are studied through experiment and theoretical analysis.
