高频逆变式整流焊机电源是一种*性能、*效、省材的新型焊机电源,代表了当今焊机电源的发展方向。由于IGBT大容量模块的商用化,这种电源更有着广阔的应用前景。
逆变焊机电源大都采用交流-直流-交流-直流(AC-DC-AC-DC)变换的方法。50Hz交流电经全桥整流变成直流,IGBT组成的PWM高频变换部分将直流电逆变成20kHz的高频矩形波,经高频变压器耦合, 整流滤波后成为稳定的直流,供电弧使用。
由于焊机电源的工作条件恶劣,频繁的处于短路、燃弧、开路交替变化之中,因此高频逆变式整流焊机电源的工作可靠性问题成为*关键的问题,也是用户*关心的问题。采用微处理器做为脉冲宽度调制(PWM)的相关控制器,通过对多参数、多信息的提取与分析,达到预知系统各种工作状态的目的,进而提前对系统做出调整和处理,解决了当前大功率IGBT逆变电源可靠性。
国外逆变焊机已可做到额定焊接电流300A,负载持续率60%,全载电压60~75V,电流调节范围5~300A,重量29kg。
