摘要
变频器控制系统工作时易受外界电磁干扰,影响变频系统工作的可靠性。正确、良好的接地是消除和降低干扰的有效措施。讨论了消除变频控制系统干扰的各种接地。
The converter control system is easily disturbed by external electromagnetism when it operates. This will effect reliability of the converter system operation. Correct and fine earth is effective measures to eliminate and reduce interference. Differentee arths to eliminate interference of the converter system are analyzed.
