基于输入电压检测的Boost PFC自适应谐波补偿控制方法
Adaptive Harmonic Compensation Control Method Based on Input Voltage Detection of Boost PFC Converter
摘要
Abstract
The traditional power factor correction(PFC)converter can only control itself to avoid causing harmonic interference to the power grid,but it cannot improve the total harmonic distortion of current flowing into the power grid at the point of common coupling of local distribution network.To solve this problem,an adaptive harmonic compensation method based on a Boost PFC converter is proposed.By detecting the input voltage and further adding harmonic compensation components to the input current,the harmonic current flowing into the power grid at the point of common coupling can be offset while ensuring the PFC function of the converter.The current controller is designed as a combination of an embedded repetitive control link and single-zero single-pole compensation to achieve small steady-state errors.At the same time,by adding a repetitive controller and a band-pass filter to the reference current signal generation link,a harmonic compensation reference current signal can be generated adaptively under different grid impedance conditions.The small signal modeling method is also used to prove that the input impedance of the PFC converter under the proposed control method is effectively reduced at each harmonic frequency.Finally,a 500 W experimental prototype was built to verify the correctness and feasibility of the theoretical analysis.关键词
