In this paper. a refined reference current generation algorithm based on instantaneous power (pq) theory is proposed. for operation of an indirect current controlled (ICC) three-level neutral-point diode clamped (NPC) inverter-based shunt active power filter (SAPF) under non-sinusoidal source voltage conditions. SAPF is recognized as one of the most effective solutions to current harm... https://parisnaturalfoodes.shop/product-category/brown-flax-seed-ground/
