用场效应管作为功率开关元件的调制式高频脉冲TIG焊电源，该电源具有60KHz的开关频率，脉冲电流频率在0．5～14Hz范围内连续可调。该机的组成及工作原理，并对开关电源中防止寄生振荡及抗干扰等问题进行了讨论。
The FET is used as a modulated high-frequency pulsed TIG welding power source for the power switching element. The power supply has a switching frequency of 60 KHz and the pulse current frequency is continuously adjustable within the range of 0.5~14 Hz. The composition of the machine and working principle, and switching power supply to prevent parasitic oscillation and anti-interference issues were discussed.
