style="text-indent:25px">常用調(diào)光方法的工作原理 1、脈沖寬度調(diào)制（PWM）調(diào)光法這種調(diào)光控制法是利用調(diào)節(jié)高頻逆變器**率開(kāi)關(guān)管的脈沖占空比，從而實(shí)現(xiàn)燈輸出功率的調(diào)節(jié)。半橋逆變器的比較大占空比為0.5，以確保半橋逆變器中的兩個(gè)功率開(kāi)關(guān)管之間有一個(gè)死時(shí)間，以避免兩個(gè)功率開(kāi)關(guān)管由于共態(tài)導(dǎo)通而損壞。這種調(diào)光控制法能使功率開(kāi)關(guān)管導(dǎo)通時(shí)工作在零電壓開(kāi)關(guān)（ZVS）狀態(tài)，關(guān)斷瞬間需采用吸收電容以達(dá)到ZCS工作條件，這樣即可進(jìn)入ZVS工作方式，這是它的優(yōu)點(diǎn)，同時(shí)EMII和功率開(kāi)關(guān)管的電應(yīng)力可以明顯降低，然而，如果脈沖占空比太小，以致電感電流不連續(xù)，將會(huì)失去ZVS工作特性，并且由于供電直流電壓較太小，以致電感電流不連續(xù)，將會(huì)失去ZVS工作特性，并且由于供電直流電壓較的工作可靠性降低并加大EMI輻射。LED，就選上海先盛照明電器有限公司，用戶的信賴之選，歡迎您的來(lái)電！</p><div
