| Abstract: | A novel one-cycle control strategy for active power filter(APF) is proposed to improve its performance,which is inspired by the finding that source current should oscillate near zero point by using classic one-cycle control scheme for APF based on unipolar operation.It employed ip-iq based algorithm to isolate the load foundational current and took the foundational component of load current as tracking object.So the circuit of single-cycle control for APF was made up of foundational component isolation of l... |
