最近在看《精通開關(guān)電源設(shè)計(jì)》這本書然后有幾個(gè)問題關(guān)于r的....1、大家平時(shí)實(shí)際做開關(guān)電源時(shí)r選擇是多少?理論值0.4么?2、若某個(gè)開關(guān)電源設(shè)計(jì)時(shí)規(guī)定r應(yīng)為0.3,而實(shí)際設(shè)計(jì)時(shí)又達(dá)不到,那么請問r是選大于0.3好還是小于0.3好?那又如果某個(gè)開關(guān)電源設(shè)計(jì)時(shí)規(guī)定r應(yīng)為0.45,而實(shí)際設(shè)計(jì)時(shí)又達(dá)不到,那么請問r是選大于0.45好還是小于0.45好?3、EMI大家在做電源時(shí)考慮得多么? |
