新型LED驱动电源设计

The Design of the New LED Drive Power

新型LED驱动电源的设计与现有分立元件搭建的LED驱动电源,本质上都是运用高频开关电源实现,所不同的是新型LED驱动电源采用高频模块(隔离式正弦振幅转化器)搭建,频率可达到1MHz以上,实现高功率密度的LED驱动电源。

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 implement,the 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。
