本文提出了一种新的谐波检测方法，以减少应用在三相有源电力滤波器的直流电容器两端的电压波动。本文的理论分析推导出传统谐波检测方法的误差以及由于瞬时负载变化而产生的直流电容电压波动。该方法在谐波检测中引入了一个新的传递函数来补偿检测误差。实验结果表明，该方法能有效地抑制直流电容电压的波动。结果表明，该方法可以将三相有源电力滤波器中直流电容的电容量降低到1/7。
This paper proposes a new harmonic detection method for reducing voltage fluctuations applied across the dc capacitor in three-phase active power filters. The theoretical analysis in this paper derives the error in a conventional harmonic detection method and the resulting dc capacitor voltage fluctuations due to transient load changes. The proposed method inserts a new transfer function for compensating the detection error into the harmonic detection. It has been confirmed that the proposed method can suppress the dc-capacitor voltage fluctuations in experiments. As a result, the proposed method can reduce the capacitance of the dc capacitor in three-phase active power filters to 1/7.
