| 摘 要： | 由于IGBT（Insulated gate bipolar transistor)较其它电力电子器件开关频率高，载流容量大，开通损耗小，饱和压降低等优点，已逐渐成为逆变焊机的主流，为了提高IG-BT逆变电源的可靠性，设计了本脉冲反馈技术的控制电路，该电路实现整个电弧负载变化范围内焊接电流的无超调快速控制，既可满足焊接静特性和动特性要求，又可保证逆变弧焊电源的可靠性，本电路适用于单端正激式，半板式和全桥式逆变焊机等。

| Abstract: | Compared with other power switcher,IGBT( insulated gate bipolar transistor) has rapider switch speed and collector current is more, collector to emitter saturation voltage is less so it is widely used in inverter welding machine. To improve welding machine reliability, present pulse control circuit for inverter is designed ,which is based on the treatment for instantaneous signal of welding current. Rapid regulation without overshoot of welding current can be realized in the whole range of arc load. It can meet the requirement of varied welding process and ensure the performance reliability of inverter. The circuit also may be used in half-bridge, full bridge and single ended forward inverter. |
