新型LED驅(qū)動(dòng)電源設(shè)計(jì)

摘要：摘要：新型LED驅(qū)動(dòng)電源的設(shè)計(jì)與現(xiàn)有分立元件搭建的LED驅(qū)動(dòng)電源，本質(zhì)上都是運(yùn)用高頻開關(guān)電源實(shí)現(xiàn)，所不同的是新型LED驅(qū)動(dòng)電源采用高頻模塊（隔離式正弦振幅轉(zhuǎn)化器）搭建，頻率可達(dá)到1MHz以上，實(shí)現(xiàn)高功率密度的LED驅(qū)動(dòng)電源。 敘詞：關(guān)鍵詞：高頻模塊 高功率密度 LED驅(qū)動(dòng)電源 Abstract：Abstract: Both of the design of the new LED drive power and the existing discrete component of the LED drive power are essentially using high frequency switch power to implementthe difference of the design of the new LED drive power is set up of high frequency module (isolation type sine amplitude converter),and the frequency can reach above 1MHz ,Finally it can achieve high power density of the LED drive power Keyword：Key words: High frequency module, High power density, LED Drive power
