摘要

与直流控制的有源电力滤波器（APF）相比，间接电流控制的有源电力滤波器（APF）结构更简单，可直接调节电网电流，因此更受青睐。然而，与直流控制不同，间接电流控制没有明确的电流参考，给限流操作带来了困难。本文提出了间接电流控制 APF 的限流控制策略。通过在 APF 输出电流的闭环控制中加入谐波谐振控制器，可使输出电流的谐波分量小于非线性负载电流的谐波分量。实验验证了所提出的限流控制的有效性。

Current-Limiting Control Strategy for Indirect-Current-Controlled Active Power Filter

Indirect-current-controlled active power filter (APF) is preferable compared with the direct-current-controlled APF due to its simpler structure and its direct regulation of the grid current. However, unlike direct current control, indirect current control does not have explicit current reference posing difficulty on current limiting operation. This letter proposes a current-limiting control strategy for indirect-current-controlled APF. By adding harmonic resonant controllers into the closed-loop control of the APF's output current, the harmonic components of output current can be smaller than that of the nonlinear load's current. The effectiveness of the proposed current-limiting control is verified by experiments.
