摘　　要：分析了一种可以降低有源部分容量的有源电力滤波器没有在实际中得到应用的原因。提出了基于双 dq 变换的控制方法,在此方法下,不管电网电压和负载电流是否平衡,逆变器都只要承担电网谐波电流和提供谐波压降,大大地降低了有源部分的容量,提高了整机的效率。5kW 负载的模型试验证明了新方法的可行性。The reason why the series hybrid active power filter with fundamental current bypass channel has not been put into practical use is analyzed. A new control scheme based on double dq transformation is proposed, by which the Voltage Source Inverter (VSI) delivers the harmonic power only, in balanced as well unbalanced conditions. So the required rating of the active filter can be much smaller than that of conventional one and the efficiency is increased. Experimental results with 5kW prototype show that it is suitable for high power harmonic suppression.
