| Abstract: | The paper analyzes several EMI modes during the charging and discharging periods of the power system of the 4×2 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 were adopted. The whole system runs more safely, stably and reliably after adopting these measures. |
