A new double single-endedforward arc welding power inverter with IGBT as power device and current PWM controller is introduced in this paper.
提出了一种新型的双重单端正激式弧焊逆变电源,采用IGBT为开关器件,引入了电流型脉宽调制控制器。

It is clear that the traditional single-endedforward converter is difficult to adapt to the trend, so, it is necessary to find a novel topology.
很显然,传统的单端正激变换器很难适应这一发展趋势,因此,必须找到一种新型的拓扑结构。

But, despite its merits, the traditional single-endedforward converter has some shortcomings, such as simple circuit, low parts count, low output ripple, etc, it also has some shortcomings.
