【摘要】 以P89LPC933为主控芯片,利用Beckhoff系列产品模块作为操作界面,以IGBT为核心逆变器件,开发了工作频率为20kHz的数字化逆变焊接电源系统。进行了电源焊接工艺实验,测试了电源的暂载率、主要工作波形,分析测试结果表明,所设计的系统合乎标准。更多还原

【Abstract】 With P89LPC933 as main control chip,Beckhoff module as interface and IGBT as inverter,we develop a digital inverted welding power source working at 20 kHz.The welding technique experiment for the power supplies is carried out,and the results show that the temporary load rate and operation curves meet the needs of standard rule.更多还原
