摘　　要：阐述了一种含基波串联谐振电路,减小逆变器输出容量的混合有源滤波器工作原理.采用基于瞬时无功功率理论的ip-iq法检测谐波电流,并运用电流跟踪控制的三角载波法控制有源逆变器.在PSCAD/EMTDC下建立混合有源滤波器模型,通过仿真分析可知谐波治理和补偿达到了理想效果.A new type of HAPF is expatiated including a fundamental series resonance circuit which decreases the capacity of inverters, ip-iq method based on instantaneous reactive power theory is used in detecting harmonic currents and triangle current tracking control method is used to control the active inverter switch, thus enchancing the control accuracy. A HAPF model is created based on PSCAD/EMTDC, the simulation result proves that the capacity of active power filter is decreased, and better performance in harmonic suppress and reactive power compensation is obtained.
