What is it about?
This paper aims at the problem that the average current is no longer proportional to the input voltage after the Boost PFC converter in the critical conduction mode passes through the zero value, which leads to the deterioration of the total harmonic distortion.

Why is it important?
The control strategy improves the effect of power factor correction and can effectively reduce the total harmonic distortion value.
Perspectives
This paper presents an improved compensation time control method and circuit based on the BOOST PFC converter. After experimental verification, the improved compensation time control method and circuit realize the positive relationship between input current and the input voltage, and achieve the high efficiency and close to 1 power factor, which can improve the power factor correction and reduce the total harmonic distortion value effectively.
