摘　　要：分析了变频调速系统的噪声源及其危害。着重介绍了变频调速系统中采取的抗电磁干扰措施(包括减少噪声源和抑制噪声在传导路径上的传播等)。结合实际电路,给出了抑制电源高次谐波的措施。Noise sources and its harmful effects of variable frequency variable-speed system were analyzed. The electromagnetic anti-inference measures of variable frequency variable-speed system, including the reduction of noise sources, suppression of propagation of noise in transmit route were introduced emphatically. Aiming at the actual circuit, measures for suppressing high order harmonic of power supply were given out.
