摘　　要：　对4×2片状放大器能源系统整个充放电过程中的几种电磁干扰进行了详细的分析比较,针对这些电磁干扰,采取储能电容器一端接地、整个能源模块单点接地、预电离屏蔽以及光纤隔离等防干扰措施,消除了4×2片状放大器能源系统的电磁干扰,使整个系统运行安全、稳定、可靠。The paper analyzes several EMI modes during the charging and discharging periods of the power system of the 4 X 2 multi-segment amplifiers. In order to deal these EMI modes, the methods of grounding one terminal of the capacitor, single grounding of the whole power system, pre-ionization shielding, optic fiber isolation and other measures are adopted. The whole system runs more safely, stably and reliably after adopting these measures.
