Abstract:
The harmonics generated during the operation of electric vehicle charging piles produce harmonic amplification effect on the load side when parallel APF (active power filter) is used to manage them. This paper proposes to improve the APF detection and tracking strategy by improving the ip-iq detection and double quasi- resonant control to accurately compensate the 5th and 7th harmonics, which reduces the harmonic compensation rate and improving the APF topology to suppress the harmonic amplification effect on the load side of the charging pile by increasing the load AC side impedance by connecting a passive filter in parallel on the load side in two ways. The simulation results prove the correctness of the improved method.
