Current Detection Control of Active Power Filter under Non-Ideal Voltage Source

  • In the ip-iq current detection method of active power filter(APF), the factors influencing detection precision were analyzed.These factors include the low pass filter(LPF) and phase locked loop(PLL).To eliminate the PLL error of non-ideal voltage source,an improved ip-iq current detection method was proposed.In the proposed method,the DC voltage regulation was processed seperately.The regulated value is added to the foundamental wave current obtained with LPF and reverse transformation.Simulation results show that the proposed method depresses the influences of non-ideal source voltage on the precission of ip-iq current detection method effectively and improves the performances of APF.
