【摘要】 电容是EMC设计中应用最广泛的元件之一。实践表明:在EMC设计中,恰当选择与使用电容能解决许多EMI问题。但是,若电容的选择或使用不当,则可能根本达不到预期的目的,甚至会加剧EMI程度。本文根据EMC设计原理和不同结构电容的特点,结合相关研究的新进展,针对电容在EMC设计中的一些不恰当的认识与做法,讨论了电容在EMC设计中的应用技巧。对EMC设计具有指导作用。更多还原

【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 valuable to guiding the EMC design.更多还原
