硅整流焊机具有价格低,可靠性强等优点,因而可作为等离子喷焊机配套电源和电弧喷涂电源。由于工作于开环状态,所以外特性很软,在电弧燃烧过程中,容易受电网和负载波动等干扰,使喷焊电流不稳定,难以保证喷焊质量。最近采用TWH8751开关集成电路对ZXG —400型硅整流焊机磁饱和电抗器的激磁电流 Silicon rectifier welding machine with low prices, reliability, etc., which can be used as a plasma jet welding power supply and arc spraying power. As the work in the open-loop state, so the external characteristics of the soft, in the arc combustion process, susceptible to disturbances such as power grids and load, the spray current instability, it is difficult to ensure the quality of spray. The recent use of TWH8751 switching integrated circuit ZXG -400 type silicon rectifier welding machine magnetic saturation reactor magnetizing current
