IET Power Electronics, Volume 17, Issue 14, Page 1893-1910, 4 November 2024.This work explored the usage of a shunt active power filter (SAPF) to alleviate power quality (PQ) issues in a power system implementing a new voltage source inverter. The proposed SAPF with a new SSI and advanced control approach can surpass existing complements in capacitor voltage regulation and harmonic suppression caused by different non‐linear ...
