变频器应用中的干扰问题及抑制方法

摘要

变频器作为典型的工控产品,广泛应用于工业控制的各个领域.变频器常处于恶劣的运行环境,易受外界的电气干扰；同时对同一电网及周围电子、电气设备也易产生干扰.文章对变频器与其他电气设备间的干扰进行了分析,总结了变频器应用中抑制干扰的具体方法.%Frequency converter as a typical industrial product is widely used in industrial control fields. Frequency converter is often used in the bad environment) and is easy to be influenced by the external electrical interference; at the same time, it may interfere with the same grid and the surrounding electronic and electrical equipment. The article analyzed the interference between the frequency converter and other electrical devices and summarized specific methods of interference suppression in the application of frequency converter.
