摘要
通过对三相四线制有源电力滤波器(APF)的总结分析,建立三桥臂电容中点式逆变器的数学模型,并引入软开关技术。采用改进型ip-iq检测电路,设计了一种新型的三相四线制APF。通过Matlab/Simulink仿真表明,设计方案具有很好的谐波抑制性能,而且大大降低了整个装置的成本和功耗。
Based on analysis of the three-phase four-wire active power filter （APF）, this paper established a mathematical model of three-leg mid-point capacitor inverter, and by introducing soft switching technology, using the improved ip-iq detection circuit, designed a new type three-phase four-wire APF. Through Matlab/Simulink simulation, the simulation waveform shows that the scheme has good performance of harmonic suppression. The cost and power consumption of the new filtering equipment are decreased greatly.
