【摘要】 本文在输出电流为100A、160A、250A系列场效应管逆变式直流手工电弧焊机的基础上,对逆变主电路的型式及其工作原理进行了讨论,对PWM和PFM等综合调制技术以及限流保护、快速反馈等方案提出了见解。可供设计逆变式弧焊电源时参考。更多还原

【Abstract】 Based on 100,160,250A series field-effect tube inverter DC SMAW machines, the type and operating principle of the inverter main circuit are discussed in this paper. The ideas for the plan of synthetical modulation technique, current-limiting protection and fast feedback etc on PWM and PFM etc are put forward. The designs for inverter arc welding power sources are available for reference.更多还原
