新型LED驅動電源設計

摘要：新型LED驅動電源的設計與現有分立元件搭建的LED驅動電源，本質上都是運用高頻開關電源實現，所不同的是新型LED驅動電源采用高頻模塊（隔離式正弦振幅轉化器）搭建，頻率可達到1MHz以上，實現高功率密度的LED驅動電源。 敘詞：高頻模塊 高功率密度 LED驅動電源 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：High frequency module , High power density , LED Drive power
