A Lyapunov Stability Theory-Based Control Strategy for Three-Level Shunt Active Power Filter
Energies, 2017 The three-phase three-wire neutral-point-clamped shunt active power filter (NPC-SAPF), which most adopts classical closed-loop feedback control methods such as proportional-integral (PI), proportional-resonant (PR) and repetitive control, can only output

On Integration Policies and Schooling [PDF]
This paper proposes a reform for school allocation procedures in order to help integration policies reach their objective. For this purpose, we suggest the use of a natural two-step mechanism. The (stable) first step is introduced as an adaptation of the

Generalized one-cycle current controller for improved SAPF power quality management
International Journal of Electrical Power & Energy Systems[EN] Current controllers are used in shunt active power filters to enhance the performance of electrical power systems by improving power quality and energy efficiency. Nonlinear current controllers are preferred in systems with nonlinear and dynamic loads due to their robust and rapid tracking of varying reference currents.
