数字式重力计量设备电磁兼容性
Electromagnetic Compatibility for Digital Gravity Measurement Equipment
摘要
Abstract
The conducted electromagnetic interference (EMI) suppression method is presented by using improved noise separation network and EMI filter design based on its inductance and capacitance optimization for digital gravity measurement equipment. The radiated EMI suppression method is also studied based on transmission line common-mode current analysis. Experimental results show that the equipment can meet GB9254 standard by using the method. The parasitic parameters are degraded in the optimal EMI filter with lower cost. Moreover, the complex radiated EMI diagnosis and suppression methods, such as anechoic chamber measurement and shielding, are avoided in radiated EMI suppression for the digital gravity measurement equipment.关键词
