解决变频器在应用中的干扰问题

Converter in the Application to Solve the Interference Problem

在各个工业控制中,随着变频器的广泛应用,系统的电磁干扰日益严重,相应的抗干扰技术已经变得越来越重要。变频器系统的干扰有时能直接造成系统的硬件损坏,有时虽不能损坏系统的硬件,但常使微处理器的系统程序运行失控,导致控制失灵,从而造成设备和生产事故。要想解决首先要了解干扰的来源及传播方式,然后再针对这些干扰采取不同的措施。

In various industrial control, with the inverter extensive use of systematically increasing electromagnetic interference, and the corresponding anti-jamming technology has become inereasingly important. Inverter system, a direct result of the interference can sometimes damage the system＇s hardware, and sometimes ean not afford to damage the system＇s hardware, but often makes the system mieroproeessor to run out of control, leading to out of eontrol, resulting in equipment and production aeeidents. To solve we must first understand the sources of interference, mode of transmission, and then against such interference to take different measures.
