Generally, low-bandwidth condition of control voltage loop is used for single-phase alternating current–direct current (AC–DC) power factor correction (PFC) converter, which eliminates the influence of the second harmonic component in the output voltage on control loop but degrades the load dynamic performance. However, the high-bandwidth condition of voltage loop would cause multiharmonic distortions both in the input current and output voltage. Regarding this issue, this paper proposes a multidimensional harmonic current feedforward compensation control (MHCFC) scheme, to eliminate multiharmonic distortion of the PFC system using a high-bandwidth condition of voltage loop and improve the dynamic performance as well. In the proposed scheme, the odd harmonics of the input current are extracted through multidimensional band-pass filters and further converted into even harmonic compensation signals via the coordinate transformation, so as to offset the negative effects of the even harmonics of the output voltage. Taking boost PFC circuit as an example, a digital controlled experimental prototype is built to verify the feasibility of the proposed control scheme. The experimental results show that, compared with the traditional low-pass filter (LPF) scheme, the proposed scheme guarantees a high-quality input current while its load dynamic response is improved by about 70%.

单相交流-直流功率因数校正变换器多维谐波电流前馈补偿控制
单相交流-直流（AC-DC）功率因数校正（PFC）变换器一般采用控制电压回路的低带宽条件，消除输出电压中二次谐波分量对控制回路的影响但会降低负载动态性能。然而，电压环路的高带宽条件会导致输入电流和输出电压的多谐波失真。针对这个问题，本文提出了一种多维谐波电流前馈补偿控制（MHCFC）方案，利用电压环路的高带宽条件来消除PFC系统的多谐波失真，同时提高动态性能。在提议的方案中，通过多维带通滤波器提取输入电流的奇次谐波，并通过坐标变换进一步转换为偶次谐波补偿信号，以抵消输出电压偶次谐波的负面影响。以升压PFC电路为例，搭建了数控实验样机，验证了所提出控制方案的可行性。实验结果表明，与传统的低通滤波器(LPF)方案相比，该方案在保证高质量输入电流的同时，其负载动态响应提高了约70%。搭建了数控实验样机，验证了所提出控制方案的可行性。实验结果表明，与传统的低通滤波器(LPF)方案相比，该方案在保证高质量输入电流的同时，其负载动态响应提高了约70%。搭建了数控实验样机，验证了所提出控制方案的可行性。实验结果表明，与传统的低通滤波器(LPF)方案相比，该方案在保证高质量输入电流的同时，其负载动态响应提高了约70%。
