The Compensating of Electromagnetic Interference for the Degaussing Power Converter

舰船临时线圈消磁是消除舰艇固定磁场,提高舰艇反磁探反磁性武器能力的重要措施。由于消磁工艺的特殊性,对于挂接于电网输出大功率电流脉冲的消磁电源有可能给电网造成极大的电磁污染,导致电网电压畸变。本文从探讨电网电压畸变的成因出发,着重研究了电压畸变的补偿问题,以期改善消磁电源的电磁兼容性能。

To reduce the magnetic detectability of vessels, the permanent ship＇s magnetism must be disposed by means of degaussing. While the power converter generates the magnitudinous degaussing voltaic impulse, the electromagnetic interference（EMI） to the grid is hard to avoid. Based on the study of the voltage disturbance process,the measures of mitigating the voltage disturbance was discussed to protect the other electric power facilities against EMI.
