An Active Power Filter in Phase Coordinates for Harmonic Mitigation

摘要

In this contribution, an efficient active power filter (APF) technique in phase coordinates $abc$ is proposed, which can mitigate the harmonics generated by nonlinear components and loads. It avoids the transformation between different frameworks and allows a control circuit design to be relatively simpler and easier to implement. The effective operation of the proposed APF is demonstrated and the potentials are illustrated with a case study.
