低成本降低开关电源(SMPS)EMC的方法 把SMPS开关频率设计成非固定,让其围绕某个频率附近不断变化,那么其EMC电磁波普将会扩散开去,将不会在开关频率及其倍频处产生很大的尖峰。 上传者:weixin_38620734时间:2020-10-20 SMPS flyback desgin guide This paper presents practical design guidelines for off-line flybac...

for over current protection, you should design the transformet , let viper work at hiccup mode at over current condition. thanks 问:在用VIP12时,发现其D极的尖峰很高,就像变压器的漏感很大一样,可是变压器的漏感已经做得很小了,这导致在测试EMC时,很多频点超标;另外,用VIP12时,其输出在空载时,输出电压...
