| Abstract: | Capacitor is the one of the elements most in use in EMC design.It has been proved that choosing and using capacitors properly can solve many EMI problems.However,choose or use capacitors improperly,and the capacitors and the relevant units with capacitors will not be able to suppress EMI effectively.Based on the principle of EMC design and the characteristics of different kind of capacitors,considering the some new achievements of relevant research and the some unreasonable applications of capacitors in EMC design,application techniques of capacitors in EMC design are studied in this paper. This is voluable to guiding the EMC designc |
