高频无极灯电源端子骚扰电压整改实例
A Rectification Example of the Mains Terminal Disturbance Voltage
of an Electrodeless Discharge Lamp
摘要 针对高频无极灯不易合格的电源端子骚扰电压项目,通过采取增加地线、修改滤波电路元件及参数、截断地环路等整改措施使其满足GB 17743—1999要求,并分析整改措施所依据的原理,给出在元件选择、参数选用和PCB走线方面的整改思路。

Abstract For the EMC test item—mains terminal disturbance voltage of high frequency
electrodeless discharge lamp,which fails usually,the measures of adding ground line,
changing some components and amending their parameters,cutting off the ground
circle are taken to rectify it until it fulfills the requirements of GB 17743—1999.
Furthermore,the theories which the rectification measures depend on are analyzed and
the rectification clues of components and their parameters selection,PCB layout are
given to readers.
Keywords electrodeless discharge lamp;mains terminal disturbance voltage;
