摘要
利用脉宽调制（ＰＷＭ）移相控制原理和结合软开关准揩振技术的优点，形成一种“软开关－ＰＷＭ”技术，并将该技术应用于逆变式弧焊机中。介绍了该逆变式弧焊机的构成，工作原理及特点。
This paper derives a kind of soft-switched PWM technique from the benefits of both the soft-switched quasi-resonant converter and pulse-width-modulated (PWM) techniques by utilizing PWM phase-shifted control, and which is applied to inverter for arc welder. The paper introduces the configuration, principle and characteristics of the inverter for arc welder.
