摘要
介绍一种用于薄板ＴＩＧ焊的逆变电源。该电源采用ＰＷＭ 和ＰＦＭ 混合调制的控制方式，引弧为ＰＦＭ 降频调制的小电流接触引弧方式，引弧过程安全可靠，通过对高频脉冲的低频调制达到控制线能量的目的。
A kind of inverter TIG welding power source for thin plates welding is introduced.Its control method is PWM and PFM modulation.The adoption of PFM decreasing frequency modulation and touch starting arc is safe and reliable.Linear energy can be controlled by low frequency modulation to high frequency pulse.
