This paper derives the relationship between the storage capacitance and the bus ripple voltage, when the LED is driven by the bias of the sine wave current and PWM current. 本文详细推导了输出驱动电流为两种脉动电流(有偏置的正弦波叠加形式和PWM方波形式)的情况下,储能电容容值和储能电容电压纹波大小的关系。
In other words, the output storage capacitance can be reduced with the same output voltage ripple. 在输出电压脉动相同的情况下,可以减小输出储能电容。
