摘要
逆变技术在电焊机主电路拓扑结构上的应用,给电焊机的发展带来了极大的推动力,但又产生了新的问题,即电磁干扰。输入整流、滤波、逆变等环节是电焊机主电路产生电磁干扰的主要来源。同时,来自电网的杂波信号则会降低逆变焊机主电路工作的可靠性,这是逆变电焊机主电路E MC急需具体解决的问题。
Inverter technology applied in main circuit has become a powerful motivator for the development of welding power supply system,but it also brings the new problem of electromagnetic interference,most of which is from input rectifier,filter and inverter. In addition,disturbed signal from the electricity grid system could reduce the working stability of main circuit. This is urgent to be solved for EMC on the main circuit of inverter welding power supply.
