A Refined Self-Tuning Filter-Based Instantaneous Power Theory Algorithm for Indirect Current Controlled Three-Level Inverter-Based Shunt Active Power Filters under Non-sinusoidal Source Voltage Conditions

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

Analysis of pit latrine microbiota reveals depth-related variation in composition, and key parameters and taxa associated with latrine fill-up rate

Pit latrines are used by billions of people globally, often in developing countries where they provide a low-tech and low-cost sanitation method.However, health and Nursery Decoration social problems can arise from a lack of emptying or maintenance of these facilities.A better understanding of the biological and environmental parameters within pit
