弧焊电源的制造从十九世纪开始至今已经历了弧焊电机、交流弧焊变压器、硅整流器、逆变弧焊电源为代表的四个发展阶段。逆变弧焊电源自70年代问世以来,由于它与传统的弧焊电源相比具有动态特性好、体积小、重量轻、高效、节能、焊接质量高等一系列优点,已成为国内焊接电源的发展方向。最初的逆变弧焊电源是采用晶闸管为功率器件,逆变工作频率低,一般约3KHZ。随着高频新型大功率电力电子器件的发展,逆变弧焊电源的逆变工作频率由于采用GTR、MOSFET?和IGBT提高到20KHZ以上,逆变焊机的发展随着控制技术的不断成熟、动态分析理论的不断深
Arc welding power source manufacturing since the nineteenth century has gone through the arc welding motor, AC arc welding transformers, silicon rectifiers, inverter arc welding power represented by the four stages of development. Inverter arc welding power supply since the advent of the 70’s, compared with the traditional arc welding power source has a good dynamic characteristics, small size, light weight, high efficiency, energy saving, high quality welding a series of advantages has become the development of welding power source direction. The first inverter arc welding power supply is the use of thyristors for power devices, inverter low frequency, usually about 3KHZ. With the development of new high-power high-power power electronic devices, inverter inverter welding frequency inverter operating frequency due to the use of GTR, MOSFET? And IGBT increased to 20KHZ above, inverter welding machine development With the control technology continues to mature, Dynamic analysis of the theory of deepening
