This flyback voltage is sufficient to light the LED.
这个反激电压足以点亮led。
As it can be seen the voltage spectrum of the 800v quasi resonant flyback is higher at frequencies below 1 MHz, and is getting lower above 1 MHz compared to both 600v designs.
和600伏特设计比较，800伏特准谐振反激变换器的电压频谱在1兆赫兹以下更高一点，在1兆赫兹以上开始变小。
However if the active clamp flyback converter is designed to operate in CCM, and the duty cycle is controlled to make the input current track input voltage, the input power factor can be improved.
但如果设计反激有源箝位电路工作在电流连续模式，控制占空比，使输入电流跟随输入电压，可以提高输入功率因数。
