Hybrid Active Power Filter for Power Quality Improvement
International Journal of Innovative Research in Computer Science & Technology, 2022 A Deadbeat current controller for an LC-coupling hybrid active power filter is proposed, which can track with the reference compensation current with low steady- state error and fast dynamic response. Moreover, it can lead Hybrid Active power Filter to be operating at a fixed switching frequency with low output current ripples, thus reducing the size ...
