晶体管式弧焊电源是另一种重要的电子弧焊电源。一、晶体管式弧焊电源的概况晶体管式弧焊电源,也称晶体管式弧焊整流器。它的发展可以追溯到六十年代中后期,但作为大功率晶体管式弧焊电源的研制,则始于七十年代初。现在它已发展成为品种多、性能好、精度高、控制灵敏并能满足各种新弧焊工艺需要的新型弧焊电源。就其主要电路而言,主要的特点是在变压整流的直流端串入并联工作的大功率晶体管组。这种弧焊电源的外特性、调节特性(规范调节)、电流电压的输出波形,是依靠大功率 Transistor arc welding power supply is another important electronic arc welding power supply. First, the overview of transistor-based arc welding power transistor arc welding power supply, also known as transistor-type arc welding rectifier. Its development can be traced back to the late sixties, but as the development of high-power transistor arc welding power source, it began in the early 1970s. Now it has developed into a new variety of arc welding power source with many varieties, good performance, high precision, sensitive control and can meet the needs of a variety of new arc welding process. In terms of its main circuit, the main feature is the series of high-power transistors operating in parallel in the DC side of the transformer rectifier. This arc welding power supply external characteristics, regulation characteristics (regulate regulation), the output voltage and current waveforms, is to rely on high-power
